A secure ring with a sound effect that ensures a ringing tone.

According to the bell-and-roll movement, which has been a long-standing folk sports in China, in order to prevent my inherent traditional culture from disappearing in the century of technological advancement, the creator began to study and promote folk sports in the Zhongzheng National Middle School in Keelung City in the 64th year of the Republic of China. The school is a key development school for folk sports designated by the Ministry of Education. A special class of "folk sports bells and skipping classes" was established in the school. Due to good results, each year, the country was selected to be invited to visit the world. It is located in the world's five continents and is well-known at home and abroad. It is currently the most famous school in the folk sports industry. This creator is the only one in the country to win the "payroll award" in the skipping and ringing project. There are quite a few things about skipping.

In order to play the rattle, there is a need to have a very high balance of the balance of the heart, so that the rattle can be rotated stably and the fancy changes of various kinds of rattles are made. Therefore, there is often a situation in which the bell is dropped when playing, and the bell is used. For the structure, for example, Patent Notice No. 120601 "Improvement of Tear Structure" and No. 354908 "Improvement of Tear Structure", the body structure of the exposed bells is mostly made of hard materials, and the current emphasis on safety toys is 21 In the century, all sports equipment should first consider its safety, especially in the ringing activities. The most populous people participating in the activity are the middle and small students of the nationality. Especially in the current new national school physical education curriculum, the folk sports have been officially included in the curriculum, and its safety has become an important topic that cannot be ignored. In the past forty years of teaching, I have found that students often throw tricks when throwing, picking up, or operating difficult pulls, and the chance of the bell hitting the head. Very high, the body of the bell rushed to the head, the blood flow to the face, causing the head to rupture must be immediately sutured, safely worried, invisibly causing obstacles in the promotion and inheritance, and the bell body often damages due to falling on the ground .
