Confucius said: When four people walk together, they must have basic feelings. Li Chicheng, Xia Muching, Murong Yun, Jin Moyu, two men and two women, the pure, exciting and never-giving-up friendship between us four sisters, the entanglement of love and hate. In this chaotic and corrupt era, many things cannot be repeated, but they make us stronger to go on. Who said: Maybe a person has to go a long way and experience countless sudden prosperity and desolation in life before he becomes mature. I don't know what our ending will be, but as long as you are still here, it will be fine. Being in the same body as you, this life is enough.
