Ace vs Ace Huang Lei's teacher-student relationship is which issue?

This program is the eleventh issue of the second season.

The theme of this program is "war at home". Huang Lei, who temporarily replaced Huang Zulin, together with Liu Jiamin, Daxun Wei and kirsten, formed a "problem family" and a "kidnapper family" composed of PK Roy, Xu, Bai Baihe, Ming Dow and Sha Yi. As a surprise guest, Li Jie also led the students of the Performance Department of Grade 97 to present a surprise session for Mr. Huang Lei.

In addition to the wonderful game PK that day, Li Jie also carefully rehearsed the surprise session for the teacher in advance, and also prepared a touching chorus that made people cry. First, everyone said a piece of drama that Huang Lei rehearsed for the students, and then the students began to sign up. In addition to the seven students present, dozens of absent students also sent sincere greetings.
