Description

Chinese character encoding and decoding method and system based on Chinese pinyin and Chinese character characteristics

Technical Field

The application relates to the technical field of computers and text input methods, in particular to a Chinese character encoding and decoding method and system based on Chinese pinyin and Chinese character characteristics.

Background

The existing input method has some disadvantages in application, such as high duplicate rate and accuracy of the shape code input method, too high learning cost and difficulty in adapting to the flow of intelligent input, being in a process of being phased out, and also has the advantages of simple and easy learning, high duplicate rate and low accuracy, and the double-spelling input method effectively shortens the coding length, but has no rule and difficulty in memorizing the corresponding relation between vowels and keys, and does not solve the problem of high duplicate rate. In addition, although some input methods introduce tone, the processing mode is rough, either keys are directly and separately set for inputting tone, or a separate state is set for inputting tone, but there are problems that the code becomes long and is difficult to analyze, and direct input ā, a and other symbols with tone cannot be supported, so that the input method supporting tone is often difficult to put into use.

Some input methods introduce other elements to improve accuracy, but often have some problems. For example, the shape codes (usually more than one hundred) are introduced on the basis of double spelling, so that the number and accuracy of effective combinations are improved, the learning cost is greatly increased, various external elements such as strokes and structures are introduced, the accuracy of inputting single Chinese characters is improved, the problem of being too complex exists, and the problems of overlong encoding and inconvenient analysis exist for words above 2 words and 2 words.

Disclosure of Invention

Aiming at the technical problems, the application provides a Chinese character encoding and decoding method and a Chinese character encoding and decoding system based on Chinese pinyin and Chinese character characteristics, which improve the matching precision of encoding and Chinese characters and the input experience of users.

In a first aspect, an embodiment of the present application provides a method for encoding chinese characters based on pinyin and kanji characteristics, including:

when the keyboard state is a first state, generating a corresponding initial consonant brevity code according to a first triggered position on the keyboard;

when the keyboard state is the second state, generating a corresponding final simplified code according to the triggered second position, the triggered third position and the triggering sequence on the keyboard;

in any keyboard state, if the fourth position which is triggered currently belongs to an auxiliary input area in the keyboard, generating a corresponding Chinese character starting code according to the fourth position, and switching the keyboard state into an auxiliary input state;

When the keyboard state is an auxiliary input state, generating a corresponding Chinese character feature code according to a fifth position triggered in the auxiliary input area;

When the input is completed, the generated initial simplified codes, the generated final simplified codes, the initial codes of the Chinese characters and the Chinese character characteristic codes are combined to construct Chinese character codes according to the code generation sequence.

The embodiment of the application provides a Chinese character coding method based on Chinese pinyin and Chinese character characteristics, which is characterized in that initial consonant simple codes, vowel simple codes, chinese character initial stroke codes and Chinese character characteristic codes are respectively generated under different keyboard states, and are sequentially combined to form a complete Chinese character code. The embodiment effectively integrates the pinyin characteristics and the structure characteristics of the Chinese characters, so that the codes can reflect pronunciation and character shape characteristics, and the duplication code rate is obviously reduced. For example, in the traditional pinyin input method, homophones are numerous, so that a user needs to frequently turn pages to select a target Chinese character, but in the embodiment, initial consonants and final sounds in pinyin codes are distinguished by introducing initial information and structural features, candidate Chinese characters with high possibility can be quickly screened out in a subsequent decoding stage, the searching time of the user is greatly shortened, and the matching precision of codes and Chinese characters is improved. And secondly, the embodiment adopts a dynamic coding mechanism in different states, so that different codes can be generated on the same key position under different input states, the occupied space of the keyboard layout is greatly reduced, and the simplicity and the attractiveness of an input interface are improved. In addition, the embodiment also designs an auxiliary input area, and a user can code structural characteristics of the current Chinese characters at any time by triggering the auxiliary input area according to requirements, so that the user does not need to frequently switch modes in the input process, the operation is smooth and natural, and the input experience of the user is improved. Finally, as the coding rule gives consideration to the naturalness of pinyin and the structural property of Chinese characters, the learning threshold is lower, and a user can master the use method in a shorter time, so that the input experience of the user is further improved.

Further, when the keyboard state is the second state, generating a corresponding final simplified code according to the triggered second position, the triggered third position and the triggering sequence on the keyboard, including:

Generating a corresponding second character and a corresponding third character according to the second position, the third position and the triggering sequence on the keyboard;

Determining a tone and a tone position according to the second character and the third character;

and generating corresponding final simple codes according to the tone positions of the second character, the third character and the tone positions.

The embodiment of the application provides a generating mode of a final simple code, in particular to a method for constructing a final code with tone by utilizing a combination mode of a second character and a third character. Specifically, the embodiment skillfully solves the problem of difficult tone input in the traditional input method. In the prior art, the tones are marked by adopting independent key positions or complex switching modes, so that the complexity of operation is increased, and error input is easily caused. In contrast, the method can realize tone embedding through simple combined action, so that a user can intuitively and rapidly complete input of vowels with tones. For example, the user can automatically synthesize the correct final form by pressing two related keys in turn, so that the complicated input flow is avoided. In addition, the design can be compatible with various tone changes, supports direct input of special characters such as ā, a and the like, is rare in the existing input method, and has obvious technical innovation. In conclusion, the introduction of the vowel coding mechanism greatly enriches the functions of an input method, improves the matching precision of codes and Chinese characters and the input experience of users.

Furthermore, the Chinese character initial stroke code corresponds to Chinese character initial stroke information, and the Chinese character initial stroke information is 'horizontal', 'vertical', 'left-falling', 'dot' and 'folding'.

The embodiment of the application defines five basic stroke starting types corresponding to the Chinese character stroke starting codes, namely 'horizontal', 'vertical', 'left-falling', 'point' and 'folding', and the stroke starting types cover the initial stroke forms of most Chinese characters, so that the embodiment can increase the morphological characteristics of the Chinese characters in the Chinese character coding process, simultaneously does not occupy more key positions, and ensures the simplicity of the Chinese character coding process. In practical application, a user can quickly select a corresponding initial code according to the writing habit of the target Chinese character, so that the input efficiency of the Chinese character code is improved. Meanwhile, the learning difficulty of the user is reduced, because the initial stroke information accords with the visual cognition of people on the structure of the Chinese character, and no additional memory of complex rules or complete strokes of the Chinese character is required. In the subsequent decoding process, the introduction of the initial stroke code further compresses the search space, accelerates the matching process of Chinese characters and improves the matching precision of the code and the Chinese characters.

In one possible implementation manner, the Chinese character feature code corresponds to Chinese character feature information, and the Chinese character feature information is a first feature, a second feature, a third feature or a fourth feature;

the first characteristic is that the target Chinese character to be encoded can be split into two or more first independent components left and right, and any one of the first independent components can be split into two or more second independent components up and down;

The second characteristic is that the target Chinese character can be split into two or more first independent components left and right, and each first independent component cannot be split into two or more second independent components up and down;

the third characteristic is that the target Chinese character cannot be split into two or more first independent components left and right, and the target Chinese character can be split into two or more second independent components up and down;

the fourth characteristic is that the target Chinese character can not be split left and right, but also can not be split up and down.

The embodiment of the application provides four Chinese character characteristic information, and the characteristics describe the structural attribute of the Chinese character based on whether the Chinese character can be split left and right or up and down, so as to provide a retrieval basis for the subsequent Chinese character matching process. The embodiment of the application provides a hierarchical structure framework for Chinese character coding, so that each Chinese character can be accurately classified. For example, the first feature is applicable to complex words with relatively complex structures, such as "inert", "Shao", etc., and the fourth feature is applicable to Chinese characters with relatively simple structures, such as "Ding", "Guo", "Shao", etc. Compared with the traditional single-dimension coding method, the multi-dimension feature coding of the embodiment captures all the features of the Chinese characters more comprehensively, so that the target Chinese characters can be positioned faster in the decoding stage, the repeated code rate of a user in the actual Chinese character input process is greatly reduced, the matching precision is improved, the memory habit of the user on the Chinese characters is met, and the input experience of the user is improved.

In one possible implementation manner, the first character and the second character in the final simple code are triggered and generated by different input areas respectively, specifically:

when the keyboard state is the second state, generating a corresponding first character according to the triggered second position on the keyboard;

in any keyboard state, if a third position which is triggered currently belongs to an auxiliary input area in the keyboard, generating a corresponding second character according to the third position, and switching the keyboard state into an auxiliary input state;

When the keyboard state is an auxiliary input state, generating corresponding Chinese character initial codes and Chinese character feature codes according to the triggered fourth position and fifth position in the auxiliary input area in sequence;

and generating the final brevity code according to the first character and the second character.

The embodiment of the application limits the specific application mode of the auxiliary input area, and the second character of the final simple code, the initial stroke code of the Chinese character and the character characteristic code are input by multiplexing the auxiliary input area on the keyboard without adding independent special keys for different types of codes. The keyboard layout is greatly optimized, so that the keyboard can bear richer input functions in a limited screen (especially a mobile device screen) or keyboard space, the definition and conciseness of an input interface are maintained, and the interface swelling and the visual burden of a user caused by excessive keys are avoided. In addition, the embodiment allows the user to flexibly trigger the auxiliary input area to supplement the vowel supplementary information and the structural feature information (vowel second part, starting and component number classification) of the input Chinese characters according to the requirement in the process of inputting the main codes (such as the first part of the initial consonant and the vowel) or after inputting the main codes, so that the matching precision of the codes and the Chinese characters is improved. The design ensures that the coding input process is more coherent and natural, and the input experience and the operation smoothness of a user are obviously improved.

In a second aspect, an embodiment of the present application provides a method for decoding chinese characters based on pinyin and hanzi features, where the method for decoding chinese character codes generated by any one of the chinese character coding methods based on pinyin and hanzi features described in the present application includes:

Acquiring Chinese character codes;

splitting the Chinese character code into a plurality of sub-code information according to the positions of initial consonant brevity codes in the Chinese character code, wherein at most only one initial consonant brevity code exists in the sub-code information, and the initial consonant brevity code is the first bit code in the sub-code information;

Generating corresponding retrieval information through a preset mapping table according to the sub-coding information, wherein the retrieval information comprises a plurality of complete initials which are generated according to the initial brevity codes; generating a plurality of corresponding complete vowels according to the vowel simple codes if the vowel simple codes exist in the sub-coding information, generating corresponding Chinese character starting information according to the Chinese character starting codes if the Chinese character starting codes exist in the sub-coding information;

For each piece of sub-coding information, searching a plurality of corresponding candidate Chinese characters from a preset database according to the corresponding searching information;

and if the number of the subcode information is 1, displaying the plurality of candidate Chinese characters on a preset interface.

The embodiment of the application provides a Chinese character decoding method corresponding to an encoding method, firstly, the embodiment considers the condition that a user inputs a plurality of Chinese characters simultaneously, the position of an initial simple code splits the Chinese character codes possibly existing in the plurality of Chinese characters into a plurality of sub-code information, and decodes each sub-code information respectively, thereby realizing the rapid conversion from the simple code to the complete information. In the information decoding process, whether the final simple code, the Chinese character initial stroke code and the Chinese character characteristic code exist in the sub-code information or not is checked in sequence, and a plurality of corresponding complete final, chinese character initial stroke information and Chinese character characteristic information are generated, that is to say, the embodiment can still normally complete the Chinese character decoding process under the condition that one or more of the final simple code, the Chinese character initial stroke code and the Chinese character characteristic code are absent, the Chinese character matching result is displayed, and the flexibility of Chinese character input of a user is improved. And secondly, the decoded retrieval information can cover multiple dimensions such as initials, finals, strokes, characteristics and the like at most, so that the database is more accurate to inquire, the returned result is more targeted, and the matching precision of the codes and the Chinese characters is improved.

Further, the generating a plurality of corresponding complete initials according to the initial brevity code includes:

if the initial consonant brevity code is a character in a preset first character set, generating a blank placeholder as a complete initial consonant in the search information;

And if the initial consonant simple code is a character in a preset second character set, generating flat-tongue consonant and seesaw consonant corresponding to the initial consonant simple code as the plurality of complete consonants.

In the embodiment of the application, the system can be more flexibly adapted to the input habit of the user through the classification processing of the initial consonant brevity codes, and the corresponding initial consonant information can be analyzed. For example, in some cases, the user may not need to input a specific initial consonant or some Chinese characters do not have an initial consonant, and then input the characters in the first character set in the encoding stage, and at this time, generate a blank placeholder as a complete initial consonant in the search information in the decoding stage, so as to ensure that each Chinese character has corresponding initial consonant information, and ensure that subsequent search is performed normally. Secondly, for some easy-to-confuse flat-tongue sounds and uptongue sounds, the embodiment can generate corresponding flat-tongue sounds and uptongue sounds according to single letter simple codes input by a user, so that the number of input characters of the user is reduced, the input efficiency is improved, and the fault tolerance of Chinese character input is remarkably improved. For example, the user may have inaccurate pronunciation due to dialect or accent difference, and the design ensures that even under the condition of incomplete and accurate input, reasonable initial consonant brevity codes can be generated, robustness of the system is enhanced, the number of key positions is effectively reduced, the keyboard layout is optimized, simplicity and attractiveness of an input interface are improved, and more convenient and efficient interaction experience is provided for the user.

Further, if the number of the sub-code information is greater than 1, according to a preset word stock and the sequence of each sub-code information in the Chinese character code, arranging and combining the corresponding candidate Chinese characters to generate a plurality of words or phrases, and displaying each word or phrase on a preset interface.

The embodiment of the application further considers the combined display scene after the user inputs a plurality of Chinese characters at the same time, and as each piece of subcode information can be matched with a plurality of Chinese characters, when only one piece of subcode information exists, a plurality of matched Chinese characters can be directly displayed. When a plurality of sub-code information exists, the number of the arrangement and combination results of each Chinese character obtained by matching is greatly increased, and a user needs to select the Chinese character to be input from a large number of matching results, so that the use experience of the user is greatly reduced. Therefore, the embodiment intelligently combines each candidate Chinese character into a plurality of coherent words or phrases by integrating the preset word stock and combining the sequence information of each subcode, thereby greatly reducing the matching quantity, ensuring that a user can quickly select the Chinese characters to be input, and improving the matching precision of the codes and the Chinese characters and the input experience of the user.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should be noted that, the step numbers herein are only for convenience of explanation of the specific embodiments, and are not used as limiting the order of execution of the steps. In the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.

Embodiment one:

As shown in fig. 1, a first embodiment provides a Chinese character encoding method based on pinyin and character features, comprising steps S1-S5:

step S1, when the keyboard state is a first state, generating a corresponding initial consonant brevity code according to a first triggered position on the keyboard;

Step S2, when the keyboard state is the second state, generating a corresponding final simple code according to the triggered second position, the triggered third position and the triggering sequence on the keyboard;

Step S3, in any keyboard state, if the fourth position which is triggered currently belongs to an auxiliary input area in the keyboard, generating a corresponding Chinese character starting code according to the fourth position, and switching the keyboard state into an auxiliary input state;

S4, when the keyboard state is an auxiliary input state, generating a corresponding Chinese character feature code according to a fifth triggered position in the auxiliary input area;

And S5, when the input is completed, constructing the generated initial consonant brevity codes, vowel brevity codes, chinese character initial stroke codes and Chinese character characteristic codes into Chinese character codes according to the code generation sequence.

In a preferred embodiment, in step S1, the main input area of the input keyboard corresponding to the coding method is 3*8, the keys in the main input area are respectively represented by 1-1 to 3-8 (first row, first column, third row, eighth column), and a function key is commonly used at the bottom, and the coding method is suitable for a mobile touch screen operating system, and after adjustment is performed according to the keyboard, the coding method is also suitable for a general keyboard.

According to the input content, the keyboard is divided into different states, and in each state, the key and the code establish a mapping relation.

The codes input by the user through the keyboard in the first state are called "initial consonant brevity codes", and the initial consonant brevity codes comprise Q, R, W, T, Y, P, L, S, D, F, G, H, J, K, Z, X, C, B, N, M and V, wherein V represents the condition of no initial consonant of pinyin, and the corresponding relation with the layout of the keyboard is as follows:

wherein, keys 1-8, 2-8, 3-8 correspond to Λ, Φ, pi respectively in this state, these three greek letters are used to refer to these three keys, in the non-input state, clicking will input punctuation marks, and clicking these three keys in the input state will not be resolved into the initial consonants either. In addition, the embodiment of the application provides a corresponding initial simple code input rule, and for the tongue-raising sound, h is directly removed, only one character is needed to be input, for example, sh only needs to be input S, ch, only needs to be input C, zh, and only needs to be input Z, so that certain flat-tongue sounds and the tongue-raising sounds in the embodiment share the same code. For pinyin without an initial, the initial is denoted by v. For convenience of expression, the same keyboard layout will be used for illustration in this embodiment, and consonant symbols are used to represent key positions, i.e. 2-1 keys are called S keys, 3-5 keys are called N keys, and 2-8 keys are called Φ keys.

Further, in step S2, when the keyboard state is the second state, generating a corresponding final simplified code according to the triggered second position, the triggered third position and the triggering sequence on the keyboard includes:

In a preferred embodiment, the user processes the vowels before entering the Chinese character and enters the corresponding simple vowel code according to the rules that a) only the first two digits of the vowels are reserved and the rest are discarded, b) the vowels are less than two digits and denoted by v, c) vowels a, e, i, o, u, u with unvoiced vowels in the vowels are denoted by â, î, ô, e, û (u is also denoted by û), respectively. The conversion process from partial vowels to simple vowels is as follows:

Specifically, in the second state of the keyboard, the first digit of the final simplified code (also referred to as the keyboard state 2-1) is input first, and the value range is divided into two categories: 1) tone is first in the final shortcode, (e.g., a, e, o beginning final and partial ui beginning final (un, uv, in, iv)), for the following final shortcode representation: a, ā, a, o, ō, b, ǒ, o, e, ě, e, i, ī, i, ǐ, im, u, g, i, ǔ, a, ǘ, ǚ, ǜ, wherein a, e, i, o, u, a represent light sound; 2) the tone is at the second position of the final (e.g., ua, ui, uo, ue, io, ie, iu, ia etc., the tone is at the second position of the final), represented by special symbols û and î, wherein û represents the final with u beginning and tone at the second position, î represents the final with i beginning and tone at the second position.

Thus, the number of symbols corresponding to the keyboard state 2-1 is 32, u and ü are combined, light sound and one sound are combined, the number of corresponding symbols is reduced to 22, in addition, using the wave symbols of ã, ẽ, ĩ, õ, ũ to indicate tones but not limited to tones, and ã, ẽ correspond to a button, representing a or e, and not limited to tones; ĩ, õ, ũ correspond to a button, representing i or o or u, and are not limited by tone. The correspondence between the final keyboard state 2-1 and input symbols is as follows:

Furthermore, the input content of the keyboard state 2-2 corresponds to the 2 nd bit of the simple code of the final, the corresponding input range is a, e, i, o, u, r, n, v, the corresponding input range is â, the corresponding input range is e, û, î, ô, r, n and v because the vowel part is not provided with tone, the corresponding input range is û and î because the input content of the previous state is provided with tone, and the corresponding input range is a, ā, a, k, o, ō, d, ǒ, co, e, ě, e, i, ī, i, ǐ, im, u, g, m, ǔ and d. The two codes are 33 codes and more than 24 keys, so partial keys are combined, light sounds and one sound are still combined, and in consideration of the fact that the sound tone symbol is input in the last step, the sound tone symbol is input in the next step, and the sound tone symbol is input in the last step, the sound tone symbol is input in the next step, so that the key is mutually exclusive (namely impossible to be selectable simultaneously) between ā and â when the keyboard is in a state 2-2, the key is mutually exclusive between ī and î, the key is mutually exclusive between ō and ô, the key is mutually exclusive between the key and û, the symbols are combined, and the key is shared with the key because the number of Chinese characters corresponding to 'r' is less;

Wherein, the 3-7 key represents a or e and is not limited to tone, the 3-8 key represents i or o or u and is not limited to tone, and the two keys can be clicked when the tone is not clear to the user. Therefore, when the keyboard is in the second state, the corresponding final simplified codes can be generated in a combined mode according to the triggered second position, the triggered third position and the triggered sequence.

Further, in step S3, the initial code of the chinese character corresponds to initial information of a chinese character, and the initial information of the chinese character is "horizontal", "vertical", "left-falling", "dot" and "folding".

In one possible implementation manner, in step S4, the kanji feature code corresponds to kanji feature information, where the kanji feature information is a first feature, a second feature, a third feature, or a fourth feature;

In the prior art, for newly added code types (such as tone, structure, strokes, etc.), there are usually several ways to set a separate area pair specifically for inputting the code type (such as several separate keys specifically for inputting tone in many patent applications), and to add a state for inputting the code type. The former needs to set independent keys, which is not suitable for mobile terminals with limited space and can lead to low key utilization and long codes, while the latter lacks flexibility and cannot realize 'on-demand input', because a certain state is generally difficult to skip in the normal input process. Therefore, unlike the former two, the dynamic input area does not need to set an independent key, or newly add a state to the whole keyboard, but rather, a certain area is specially designated in a certain state, and has an independent sub-state, after the area enters the inputtable state, the sub-state is only changed by clicking the key, the state of the main keyboard is not changed, the input of the main code is not influenced, and the keyboard is switched to the next state by clicking the key outside the dynamic area.

Advantages of dynamic input area:

1. An input area is not required to be independently arranged outside the main keyboard, so that the keyboard is not bulked;

2. The special keyboard state does not need to be added independently, and the coding analysis difficulty is not increased;

3. The method has high flexibility, the main code and the auxiliary code are separated, the auxiliary code can be input according to the requirement, and the main code input is not influenced;

4. The method overcomes the problem of the combination input that the combination input is caused by the combination of two different types of elements, namely, the combination input is an input method for combining two different types of elements together and mapping the elements with a keyboard, such as combining the second letter (without tone) of a final simple code with the last pen of a Chinese character, clicking a key once and inputting the letter and the last pen at the same time, and has higher input mode efficiency, but the two elements are required to be combined in the brain and then correspond to the key, so that time thinking is required to be spent, and the input experience is poor;

5. Support an unlimited number of secondary codes (of course the secondary code types should not be too many to encode too long);

Setting up a dynamic input area, namely 1) designating a state corresponding to the dynamic input area, 2) reserving a fixed blank key (without setting a mapping relation) in the designated state, and 3) setting up a dynamic area sub-state, wherein clicking a dynamic area key only changes the sub-state, but does not change the keyboard state, and does not influence normal input of other keys.

In an preferred embodiment, the keyboard state corresponding to the dynamic input area is a first state, (any keyboard state can be set to trigger the dynamic input area), the keys in the dynamic area are three keys (1-8, 2-8 and 3-8) at the rightmost side in the first state, the three keys are blank keys, and the dynamic area has two sub-states, namely, the state 1-1 corresponds to the starting of Chinese characters, the state 1-2 corresponds to the classification of the number of parts.

The initial of Chinese characters refers to the first stroke of Chinese characters, which is divided into horizontal stroke (I), vertical stroke (I), left falling stroke (II), dot stroke (III) and folding stroke (yi 乚), and Chinese characters can be divided into 5 classes according to the initial of Chinese characters, for example, the initial of Chinese characters is "horizontal" and has "south", "Su", "lower", "have" and the like, chinese characters with initial strokes of I include "Japanese", "Japanese" and the like, chinese characters with initial strokes of "Japanese", "Japanese" and the like, the Chinese characters with "point" are "Song", "talking", "send", "Guang", etc., and the Chinese characters with "folding" are "silk", "nine", "pre", "aim", "good" etc.

Regarding the number of Chinese character parts classification, the number of Chinese character parts is not the number of independent parts of the whole Chinese character, but the number of parts in two dimensions in a longitudinal and a transverse direction. The classification according to the number of the parts refers to classifying Chinese characters from two dimensions of the number of the vertical parts and the number of the horizontal parts of the Chinese characters, wherein x is represented by x-y, x represents the number of the horizontal parts, y represents the number of the vertical parts, and the Chinese characters can be classified into the following categories:

The Chinese characters can be transversely divided into 2 or more independent parts, and one of the left side and the right side can be longitudinally divided into 2 or more independent parts, and the Chinese characters are recorded as 2-2, such as 'inert', 'Shao', 'shao', and the like;

The Chinese characters can be transversely divided into 2 or more independent parts, and the left side and the right side cannot be longitudinally divided into 2 or more independent parts, and the Chinese characters are recorded as 2-1, such as 'punching', 'arranging', 'digging', and the like;

2.1, Two-word assembly code rules

The codes of the two-word vocabulary are C1C2C3C1C2C3, namely the first three codes of two Chinese characters are combined together, for example, the codes of two Chinese characters are JXM Φpi and SBM Λ respectively, and the codes of the word are JXMSBM.

the first two codes of each Chinese character are taken as C1C2C1C2C1C2, and compared with the main codes of each Chinese character of 'Huiyin like torch', the main codes of each Chinese character are HNG, YRN, RXV, JBV respectively, so that the codes are HNYRRXJB;

2.4, five words and above vocabulary codes, and two coding modes exist for the five words and above vocabulary:

C1C1C1C1C1, namely taking the first position of each Chinese character code, for example, the corresponding code of 'fashion hero' is SSZYX;

the first two codes of each Chinese character are taken, for example, the main codes of each Chinese character are YBV, SBV, ZPV, BBV, DWV when the user wants to speed, so that the codes are YBSBZPBBDW.
