I have studied mountain art for eight years, and you are only in junior high school now. You should be very young. I don't know whether you studied Clouds or Man Zi. If you can still cross the front axle now, everything will be fine, not to mention sticking your head to your ass. What's more, when I was studying, my legs and waist were severely torn. You are still young, you can be saved by tearing it at will. Don't be afraid and nervous. It will be done in two days. This was our first semester at that time.
