The real dance with fire is Haidilao Hotpot Restaurant. The waiter in the store improvised a "subject three" dance, and the video was sent to the online platform, which quickly became popular.

On December 5th, the reporter interviewed the staff of Haidilao Li Jiacun Store. She said that the waiters would be arranged to dance "Subject Three" at 13:30, 19:30 and 23:00 every day, and most customers were very interested in it and found it very innovative.

"Jumping’ subject three’ makes us very high." Wang Qikun, a junior in a university in Xi ‘an, said that this dance is magical, full of energy and comfortable, and many students around me are learning. But this dance looks simple, it is not easy to dance silky and smooth, and it will sprain my ankle if I am not careful.

Previously, a "00" young man was unable to squat because of the unbearable knee pain after dancing the "subject three" dance. After medical examination, he was diagnosed as a contusion of the tibial plateau.

Dr. Yang, an orthopedic attending physician in a hospital in Xi ‘an, said that this dance is mainly supported and stabilized by the ankle joint and knee joint, and its joint structure itself cannot be as flexible as the shoulder joint or wrist joint. This set of movements requires the knees and ankles to swing flexibly while supporting stability, and the center of gravity shifts during exercise, which greatly increases the risk of joint injury. He suggested that daily exercise of core muscles can help to improve the stability of the body. Before learning to dance any dance, you should first fully warm up and increase the ductility of joint ligaments. Secondly, you should learn to master the essentials of dancing, don’t blindly follow the trend, all the actions you do should be within your own ability, and you can’t blindly pursue the effect and take risks. In case of sports injury, you should seek medical advice in time.
