At the beginning, the senior said that this class was for students who were injured or could not do strenuous exercise for special reasons, so the content of the course was similar to that of the elderly, climbing mountains, running and sword dancing (the school swords were old, rusty and heavy)
I went to school. I often run. I often go jogging. I learned a set of Tai Chi sword routines in the middle, and I am going to take part in a performance or something. Actually, it's boring, and there is no other fun. I didn't want to take such a tiring class as running at first.
