Tell me about the origin of Si Liu's sorrow.

none of the sons came to take over their classes.

Although a daughter is capable, she is a daughter after all. Because my daughter is middle-aged and unmarried, I feel sorry for her, and I let her go on weekdays, but I don't want my hard-earned property to be given to others with my daughter. So I cut off my relationship with my daughter, and finally I don't even know where my daughter's grave is. Feudal thoughts made him forget his family, and when he woke up, it was too late. I believe that when Xiangzi kicked him out of the car and stood there alone for a long time, he really felt lonely. He really felt that he had nothing but money, and even his daughter's grave could not be seen. Affection is precious. I hope we don't know how to cherish it after losing it. At that time, we can only stand in the same place for a long time like Si Liu, silently crying in the wind.
