董允
When Liu Shan wanted to have more concubines, Dong Yun pointed out that his imperial harem was already full and reminded him that according to historical precedent a ruler should have no more than 12 women in his harem. He also firmly refused to carry out the emperor's order to search for more women to join the harem. Liu Shan, unable to get what he wanted, resented and feared Dong Yun.
