高歓
In 535, Gao Huan found out that Gao Cheng had been conducting an affair with Gao Huan's concubine Lady Zheng Dache (鄭大車). In anger, he caned Gao Cheng 100 times and put him under arrest, and he seriously considered making Gao You (高浟), his son by his concubine Lady Erzhu Ying'e (Erzhu Rong's daughter) heir apparent to replace Gao Cheng. Gao Cheng sought help from Gao Huan's friend Sima Ziru (司馬子如), who persuaded Gao Huan to change his mind by reminding him the contributions that Gao Cheng's mother Princess Lou had made, and also subsequently by forcing the witnesses to the affair between Gao Cheng and Lady Zheng to recant. Still, Princess Lou and Gao Cheng were forced to repeatedly bow and crawl on the ground to beg Gao Huan's forgiveness, and Gao Huan allowed Gao Cheng to remain heir apparent.
