2.20 15 years, David participated in Hunan Satellite TV variety show "Freshman Season", and invited Mabel Yuan, David and Huang Zhizhong as mentors to teach a group of performing arts students and interns related courses. The program that didn't have a bright spot was on the hot search list because of a few angry and quarrelsome scenes.

At the beginning of the program, David was very angry. In the first stage of the program, David became very angry. The reason is that the intern Thomas didn't sign the student handbook, and David got angry directly. If you don't sign, you will leave here. David also lost his temper in the second period of this season. Yuan Yuxuan, a student, directly told him not to mix with students.
