My name is Gu Qinghe. Wandering outside for twenty years, I survived with difficulty by picking up food. By a sudden accident, I save Old Master Gu, and the plum blossom birthmark on the back of my hand reveals my swapped identity. Stepping into the Gu family, Gu Yuwei, who has occupied my identity for twenty years, obstructs me everywhere and issues false appraisals, wanting to drive me away. Father always believes in me, and a second paternity test restores the truth. The old nanny's conspiracy is exposed publicly, and with my hundred-family cloth and jade pendant, I return uprightly to the home that belongs to me.
