Historically, this Korean lady did have a daughter. When Mrs Han married Cui Ming, the couple had a daughter named Cui Shi, whose name was unknown. "Old Tang Book" records: "Guangping is the king of the times, so Xuanzong chose the daughter of South Korea and married in Guangping House, which is full of ceremonies. Call Wang Xi. When the princess took advantage of her family, she was quite jealous. She fell into the hands of thieves in Xijing, and her mother party was all punished. The princess became thinner and thinner from the king to Lingwu. This is the life of Cui Shi, one of Guangping's concubines. Cui Shi used the power of the imperial concubine and her uncle Yang. After marrying Li Chu, the king of Guangping, she was rebellious and jealous, but Li Chu didn't dislike her. Presumably forced by the situation, I can't offend Yang, but I can only endure Cui Shi's temper. Cui Shi gave birth to a child named Dai Li for Li Chu. Later, Yang Guifei's party was killed and Cui Shi's matriarchal line was removed, which made her depressed and alienated by Li Chu. She died soon after she arrived in Chang 'an.
