On the morning of the Teacher's Day in 2019, the students in the group went to the big office to send festive blessings to the teachers, and sent flowers, fruits and gifts that were purchased spontaneously. Subsequently, teachers Jun Liu (fourth from the left in the front row of the photo), Zhicong Shi (fifth from the left in the front row of the photo) and Xi Ke (nine from the left in the front row of the photo) were happily taking photos with the students in front of the office.

In the group, teachers Liu Liying and Wang Naiguang who went abroad for academic exchanges, and some students who go out for scientific experiments could not be present.
