Chinese men's badminton singles player, won the Austrian Badminton Open men's singles championship. After retiring, he now works at a university in Beijing. His physical education classes are famous for their core strength training. Oh no, yes, the teacher is famous for being handsome. The strong-minded technology in the Academic Affairs Office was about to turn into a weak-minded technology. It was better to have classes than no classes, so I chose the courses casually with a casual attitude. So I chose the last physical education class on Friday. Before class: Great, the last period on Friday is physical education, easy. After class: It was so miserable. I spent the weekend recovering my strength and crying. "Hold on, you haven't reached your limit yet." "It's good to keep your belly up!" "His legs are shaking, but you haven't shown that your muscle strength is okay." Whenever Ziwen's physical education teacher gave him a thumbs up, he would feel embarrassed. This story is purely fictitious, you can bring it in and make up your own mind
