If the seat belt is loose, the child may fall and get hurt during the performance. This situation can be avoided by properly binding the seat belt. The specific operation is: pass the belt through the hem (you can also fold the belt in half and then pass it through), and tie both ends of the belt around your waist. It should be noted that the belt should not be too tight or too loose. Proper tightness is the key to keep clothes beautiful and ensure safety. In addition, we should pay attention to the choice of children's martial arts performance costumes, and choose clothes with appropriate size, good quality and high comfort to ensure that children feel comfortable during the performance.
