The princess is the king's wife, and she used to use her parents' wealth to provide for the king. The king was beaten with a stick in Huaishuo, and his body was completely bruised. The princess fed him day and night and treated his wounds. Later, in order to escape Ge Rong, you fled to Bingzhou together.

Besides, a woman is just like a grass, and if you are a maid, you Don't believe it."

Gao Huan asked Sima Ziru to interrogate the matter. After Sima Ziru saw Gao Cheng, he scolded him and said: "How can a man falsely accuse himself out of fear of coercion?"

Gao Huan was very happy and immediately summoned Lou Zhaojun and Gao Cheng. Lou Zhaojun saw Gao Huan from a distance and kowtowed every step of the way. Gao Cheng also bowed as he walked. The father and son faced each other and cried, making peace as before. Gao Huan held a banquet to celebrate, and said: "It is Sima Ziru who reunited our father and son!"

Zheng Dache still loved her after this incident, and her younger brother also followed the chicken and dog to heaven.
