The official name is Jiamusi happy dance step, which is inherited and created. Compared with the national broadcast gymnastics, the biggest advantage is strong sense of rhythm, and the exercise time is about one hour. Because the decomposition of each section has a pause of nearly one second, I feel very unified when doing group exercises, and everyone has a strong sense of participation. This is a sport suitable for all ages. This kind of group exercise has not only become the most extensive after-dinner exercise in the local area, but also mutual encouragement among groups can keep the participants enthusiastic for a long time. It has become a local city card in Jiamusi. Yu Chuancheng, the founder, was originally a physical education teacher in Jiamusi No.13 Middle School. He has long observed and analyzed mass sports in Jiang Yan Park in Jiamusi City, so Jiamusi Happy Dance is not only a fitness exercise, but also a cultural way.
