Gao Cheng
Also in spring 535, a sex scandal affected Gao's household. Gao's heir apparent Gao Cheng, born of his wife Princess Lou, had an affair with Gao Huan's concubine Zheng Dache (鄭大車), and the affair was discovered. Gao Huan caned Gao Cheng and put him under house arrest, and refused to meet with Gao Cheng's mother Princess Lou. He also considered replacing Gao Cheng as heir apparent with Gao You (高浟), the son of his concubine Erzhu Ying'e, the daughter of Erzhu Rong who had previously been Emperor Xiaozhuang's empress. After intercession by Gao Huan's friend Sima Ziru, who reminded him how much Princess Lou had done for him before he had accomplished great things and who used violent methods to force the servant girls who were witnesses to the affair to recant, Gao Huan calmed down and did not replace Gao Cheng.
