老板，这是燕婉容。Mr. Sun Yimin's guidance to the practice team is not only reflected in practice, but also in the safety, life, study, life and other aspects of the team members. When this activity was slightly conceived, Mr. Sun repeatedly stressed with the captain the safety of the team members' stay in school, the transportation mode and route for two days out, etc. The teacher also repeatedly asked about the cost of this activity, and was very worried that some classmates would have family difficulties and could not afford the cost. On the day before the start of this summer's social practice activity, the team leader and vice-captain were worried that the content of the activity was not full enough. Teacher Sun Yimin immediately built a bridge for the team and introduced the team to Dalongfang Science Park. Within 9 days before and after the activity, two days of pre-contact and three days of probation, Mr. Sun Yimin took out the whole three days to accompany the team to three probation bases to accompany and guide the activity. Before and after each activity, in order to make the team members better transform what they have learned in practice into their own abilities, Mr. Sun Yimin encouraged the team members to actively ask questions and establish contact groups with successful people they met during the probation process, so as to facilitate better communication between the team members and role models.8.
