Why did Si Manan Star become good friends with her husband's concubine?

This story is the origin of the idiom "I pity you when I see you", which comes from Shi Shuo Xin Yu Yuan Xian. It tells the story that Li Furen saved a crisis with his charm.

In the Eastern Jin Dynasty, Huan Wen rose up, overthrew the Han Cheng regime, and married the sister of the last emperor of Han Cheng, Shi Li, as his concubine. Huan Wen liked this girl named Li very much, but Huan Wen had a wife by then. His wife is not an ordinary person, but Jin Mingdi's daughter, Princess Nankang, whose name is Si Manan Xing. Because she is a princess, she has been spoiled since childhood. Sima Xingnan's character is very tough, even Huan Wen is afraid of three points. So Huan Wen hid Miss Li in the back room, afraid to let his wife find out, and went to visit her regularly.

After all, there is no fire in the paper. Princess Nankang also knows about Huan Wen's harboring mistress. Jealousy is a woman's nature. Princess Nankang was furious. She immediately led the maid-in-waiting to break into Miss Li's room with a knife and wanted to cut the fox with a knife.

When Princess Nankang entered the door, she was stunned by the sight before her. I saw Miss Li sitting in front of the mirror, combing her hair, with graceful posture and elegant manners, like a fairy, and her beautiful black hair hanging down like a waterfall. She turned around and saw Princess Nankang standing in front of her with a knife. Fearless, she said with tears, "I was forced to marry here, but I didn't want to." Originally, I didn't intend to live. You killed me just to realize my wish. "

Princess Nankang was deeply impressed by Miss Li's rainy face, supercilious language and leisurely bearing. Suddenly, her heart melted. She hugged Miss Li and said, "I will love such a beautiful woman when I see her, not to mention my husband?" Since then, she has been very kind to Miss Li, and they get along like sisters.
