"At that time, Lu Diyin was taught by the left minister of the Ministry of Household Affairs. The emperor had a banquet with the ministers, and Diyin's wife and daughter were sitting among the seats. The emperor held the daughter in his arms, smiled and said to Diyin, 'If I get a son, I will be your son-in-law.' The daughter was only two years old and had no name. Later, she was named Xia Qing."
