Hui Zicheng has independently developed many products, and also has national utility model patents. He developed a modular rifle butt called the center of gravity, which can move the module according to the center of gravity, can be quickly disassembled, and can also reduce the weight of the gun according to personal needs, which is a godlike existence for the shooter. Hui Zicheng once used this kind of gun, and achieved good results in three positions of 50-meter rifle in training, which also exceeded the world record. Later, Cheng Huizi went abroad to compete. Some foreign players thought it was very good and wanted to buy it, but he didn't sell it. In addition to the butt, he also has five other patents for the design of sports guns.
Cheng Huizi has another wish, that is to become a carpenter. He thinks it may be because grandpa and dad are carpenters, so they have strong feelings for wood and handicrafts and dream of opening their own studio in the future. In the shooting world, Zheng Huizi's ingenuity is unique. He himself once said that filming, like a craftsman, has to do one thing and can only do one thing.
In the test of Rio Olympic Games, Cheng Huizi broke the world record and became the dark horse of Rio Olympic Games. In the following Olympic qualifiers, he missed the final in Sun Shan. The defeat of the qualifying match and the influence of injury also made him give up. But in the end, with the support of his comrades-in-arms and coaches, he persisted. Now, and Cheng Huizi have succeeded.
