I came from Nanchang, Jiangxi Province, and I came to Xi'an Smart Power Center for the first time. I was fortunate enough to participate in the training class. I deeply feel that Teacher Yang’s waist shift is very different. In a short time, you can master the mechanism of loose waist and quickly release the tail, ankle, waist and spine. In the past, I dare not imagine that loose waist is a very difficult problem to solve. This time I personally experienced and witnessed the process of loosening the waist. Yang’s method of loose waist is really amazing!
