The first class at school arrived as scheduled. Xu, the champion of freestyle skiing women's aerial skills in Beijing Winter Olympics, showed a series of tactics tables made by herself, clearly measured every jump, answered every question and analyzed every possible situation. Xu made a tactical table like 406. At only one Winter Olympics, Xu made five weather plans. "There was a lot of wind and snow in the preliminaries on the evening of February 13. Seeing this weather, I made a plan for myself first. Because of the weather, I listed five kinds. The final is still in the evening, and I still made plans for each event. At that time, a voice in my heart told me that it was possible. Even if I didn't win the championship in the end, I would like to break through again.
