First, this approach is correct. The TV series "Centimeter of Love" explains the patriarchal family well, and also shows us the problems a boy living in a single-parent family encountered when looking for a partner. The second daughter of Guan Yuqing's family, he has been forbearing his younger brother, who is a dude. He doesn't have a serious job, but only makes his father happy and asks his sister for money to spend for himself. As a captain, Guan Yuqing has a very stable job. He was treated unfairly at home, so he could go out and live alone. Therefore, in the casting of this play, I strongly support him to sever the relationship between father and daughter, which is also a punishment for his father.
Second, if I were you, I would have cut off the relationship a long time ago. Besides, I admire Guan Yuqing in this TV series because he is really patient. She moved out of the house in order to keep her brother and girlfriend together. When her brother got married, he was also willing to remove his name from the real estate license. When he needs help, he will say something unpleasant, but he is also willing to help his brother in practice. If I were in this TV series, I might have broken up with such a father in the first few episodes, because I could have lived a good life alone. Why should I suffer in this family?
Guan Yuqing gave her parents pension money when she broke up with her father. You said he gave his parents 5000 yuan in alimony every month. As a daughter, he has done his best.
