The important ministers in the court all believed that the emperor's brother had obtained the throne because of his mother and concubine, and privately treated the emperor's brother as worthless.
They called him "Young Emperor", which means child emperor, and said that he was cowardly and had no merit except inheriting the beauty of his mother and concubine.
Some ministers even ridiculed the emperor's brother, saying that the emperor's brother had a charming face, and it was because of this face that the emperor kept his position as the prince in front of his father. The implication was really unpleasant.
