Three daughters. Weng Fan's father, Weng, is from Chaoshan, Guangzhou. His family has three daughters, and Weng Fan is one of them, so their parents have three children. Two sons and a daughter both live in the United States. The three children occasionally visit their father in China and seldom live with Professor Yang. In fact, Weng Fan only needs to take care of her husband after marriage, and she doesn't have to deal with complicated family relations.
