No. Practice Committee is the manager in the practice activities organized by schools or educational institutions, and is responsible for coordinating and organizing the development of practice activities. The participation of the Practice Committee is very important, but it is not necessary to participate in every practical activity. Practitioners need to arrange their own time and tasks reasonably according to the specific situation of practical activities and their own actual situation to ensure the smooth development of practical activities. If a practice member is unable to participate in a practice activity due to personal reasons, he can explain the situation to the organizer in advance and try to arrange other members to participate instead of himself. However, if the practice committee cannot participate in practical activities for a long time, it may affect the development of practical activities and the efficiency of organizational work. Therefore, it is suggested that the practice committee should participate in practical activities as much as possible and play its role.
