It's finally my turn. Speaking of Hetang and my family, I really have something to say. Many years ago, my family met an old doctor in the crane hall. After that, the old people at home often do exercises, and when they come back, they tell us what we can't do, which is not good for our health. At that time, Xiao really didn't know how to exercise. Now that I think about it, I really want to thank the crane hall. Old people often do exercises. You can learn about it yourself and hope to adopt it.
