Did TV School 20 15 talk about how Zheng Xiuren died and how Gao Enxing's neck was injured? If so, in which episode?

That's right. In the seventh episode, Gao Enxing was injured in the neck (Lian Meitui pushed Enxing to the ground and cut his neck), and in the fourth episode, 14, Zheng Xiuren died.

Episode 7: En Fei is questioned by Jiang Xiaoying and Han Yi 'an at the same time.

Synopsis: I went home with a paper to check my father's handwriting, and Jiang's father tore it up and scolded it. When she returned to her room, Fu Jiang went to the trash can again and picked up the torn paper to check her handwriting. The school requires students to write an evaluation in teams because the previous period of students' study tour was in a unified camp. Enfei Li saw the problem from the photos of Silver Star in Tong Ying, and began to investigate what happened before Gao Enxing disappeared. Yin Sheng once met Lian Mei, because Lian Mei always received short messages from Xiuren, who had passed away. She thought it was Yin Sheng's cell phone. In the process of pushing, Gao Enxing fell to the ground and his neck was scratched.

Episode 14: Yin Sheng and Sister Xiuren reconcile Eun-fei and return to Seoul.

After Gao Enxing came back, she talked to Teacher Jin about Xiuying. She didn't want to run away. Teacher Jin also thinks that he has made more mistakes and will not hesitate to go to the police station to turn himself in and correct them. The time of death that Kong saw on the record was tampered with. When he got home at night, he took out his mobile phone and showed his father Zheng Xiuren's death record. Kong's father was taken aback and scolded Kong for meddling.

Kong Guangtai had guessed that his father had modified the time of Zheng Xiuren's death. The advantage of modifying the time of death is to prove that Zheng Xiuren didn't die at school, so that Confucius, the principal, doesn't have to bear any responsibility. Teacher Jin has long known that Confucius tampered with the time of death. After careful consideration, he persuaded Confucius that he could not continue to make mistakes.
