Who finally owned the palace lock Liancheng?

Liancheng and Hengtai are together, but when they are together, their temples are frosted, which is a pity.

The story happened during the Qianlong period. In order to keep his position, Fujin Nalan Yue Ying of Fu Cha General's Office planned to change the boy he bought into his own girl, named Hengtai, and gave birth to a daughter, who was thrown into the river by Mammy Guo that night. Fortunately, she was picked up by Song Liniang, a prostitute of Fang Yingting, and was raised by Liancheng. Eighteen years later, the stolen son Hengtai, with his confidant Xiaoguo, happened to meet Liancheng in the downtown street. After many twists and turns, it was love at first sight, goodbye and love.
