Princess Fukang is Song Renzong's favorite daughter. Because the princess is clever and filial, she always waits on the left and right when Injong is ill. Injong's love for this daughter was unprecedented in the Song Dynasty, but it was this love that ruined the happiness of Princess Fukang's life. Because Song Renzong's biological mother was Li Chenfei, Song Renzong felt that she had wronged her biological mother, so she promoted Li Chenfei's maiden to a poor level. Even to thank them, she married her favorite Princess Fukang to Wei Li, the son of Li Chenfei's younger brother Li Yonghe. Wei Li is Song Renzong's cousin, so he is Princess Fukang's cousin. This marriage, princess Fukang is unwilling and can't help it. Liang Huaiji, as the princess's attendant, accompanied the princess to marry Wei Li. But Song Renzong bought a princess mansion for Princess Fukang, so the princess lived in the princess mansion after marriage, and Liang Huaiji was the eunuch in charge of the princess mansion.
Princess Fukang doesn't like Wei Li because she is not good-looking. Influenced by Princess Fukang, the servant's attitude towards Wei Li gradually became disrespectful. One day a few years later, Liang Huaiji was drinking with Princess Fukang. Yang, her mother, was hiding and peeping, and was discovered by Princess Fukang. The princess not only beat her mother-in-law, but also ran back to the palace in the middle of the night and cried to her father Song Renzong. Ministers were very dissatisfied with what Princess Fukang had done and protested in succession. Song Renzong had to send Liang Huaiji to pacify public anger.
Afterwards, Princess Fukang was greatly stimulated and wanted to commit suicide many times. Song Renzong felt very sorry and had to recall Liang Huaiji to his palace. Since then, there has been no record of Liang Huaiji in the official history. It is very likely that he will end up alone.
