Taekwondo teachers will say something like "wipe tears" at first, and then what will we say? And why do my hind legs keep shaking when I warm up?

Taekwondo pays attention to ceremony from beginning to end. First, it salutes the national flag. Coach can speak Korean, tea! Chinese means stand at attention, and then shout lie down! This is a salute. At this point, students should put their right hand on their left chest and watch the national flag for 3 seconds. Then the coach announced the end of the ceremony, and then the teacher and students saluted. Coach called Cha Liao! Lie! The coach and students should bow and salute, and the students shouted Tai Kun! Chinese means taekwondo, and the same is true after class; As for leg shaking, it's because your body can't bear such a big training intensity. After more training, I get used to it. My physique has improved, but I'm still too nervous. You should relax and train hard. Study hard, come on!
