Are Cui Fengping and Fanxing the biological mother and daughter in April of Stars?

No, Fanxing was named Ruoxi when she was a child, and she was adopted by Cui Fengping and his wife. Later, Cui Fengping had her own daughter Fanxing, and she was very partial. Ruoxi felt very uncomfortable and deliberately abandoned Fanxing when she was four years old. Cui Fengping and his wife always thought that Fanxing was lost by themselves. Later Ruoxi replaced Fanxing and used the name Ye Fanxing.
