Singer Qin Feiyin and her rival Shen Rong gave birth to a daughter in the hospital on the same day. Shen Rong swapped the two children out of jealousy. From then on, the two children exchanged their lives. Su Wanyue (Qin Feiyin's daughter) was abused by Shen Rong in the Shen family, while Qi Daining (Shen Rong's biological daughter) enjoyed prosperity and wealth in the Qi family.
