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.
