Background
Poker (English: Poker), refers to two meanings: one is playing cards (playingcards); the second is a game played with playing items such as paper cards, which is called poker game, such as texas poker. There are 54 cards in a deck of playing cards, of which 52 are true cards and the other 2 are decks (king and queen).
The 52 positive cards are divided into 13 groups, and each group is represented by four suits of spades, peaches, clubs and squares, and the cards of each suit comprise 13 cards marked from 1 to 10(1 is generally represented as A) and J, Q, K.
Poker is a paper toy which is popular all over the world and can be entertained and played. Because of different playing methods, the traditional Chinese medicine is commonly called playing cards, Wanliu, Ma Jiu and the like and called differently. Its standard name poker is the transliteration of poker.
The origin of playing cards is not yet fully determined, but is generally considered to have evolved from french taro cards. Early playing cards were likely introduced into europe by egypt in the end of the 14 th century. K is usually considered the largest card and a the smallest card in the 15 th century. The approach of taking a (ace) as the largest and 2 as the smallest is probably started after the french revolution in the late eighteenth century. At present, the domestic practice is to play the largest ghost card for 2 times, A being the third largest, and then K.
