What episode is Dad's 80th birthday?

The first 1 1 set. Dad's main story is that he came home with four beautiful daughters, Fang Quan, Quan Wei, Quan Shui and Quan Ai. Thanks to hard work to bring them up, the only wish is that the four children can find their own happiness on their own life path. However, it seems that it is not a simple thing to realize this simple wish. Because of trivial matters in life, Fang Quan's marriage with her husband is on the verge of breaking up. Quan Wei fell in love with Du Siyuan, a single father with a daughter, and found it difficult to be a stepmother. At the same time, the emotional road of power water and power love is not smooth. What worries me most is his relationship with Huang Peony. This hard-won relationship is doomed to be blocked and stormy.
