In Yanyuntai, Xiao Yanyan became the queen of Yeluxian, while Xiaoyu appeared behind. Xiao Yu in "Clouds in Clouds" came online only later. She was born in the Bohai Sea, dressed in white, with a gentle temper, which I feel quite pitiful. Ye Luxian was in poor health and fell ill unexpectedly during Bona in the spring. Xiao Yu's father is a doctor, and Xiao Yu is good at massaging various acupoints. Because it can help Ye Luxian alleviate her physical pain, Ye Luxian took her back to the palace.
It is understood that there is no Yu Di in history, but there is a Bohai Princess beside Ye, which is somewhat similar to Yu Di. In Yanyuntai, Yu Di was set as the favorite princess of Ye Luxian's later period. In fact, the princess of Bohai Sea in history was his woman long before Xiao Yanyan married Ye Luxian, and she also gave birth to a daughter.
The story of Princess Bohai and Ye Luxian is limited to giving birth to a daughter. It's really hard to say whether she is Ye Luxian's favorite, because in history, Ye Luxian and Xiao Yanyan gave birth to seven children. After he married Xiao Yanyan, he never gave birth to another woman, which is enough to show that Xiao Yanyan is the true love of Ye Luxian.
There are only two historical records about Ye's empresses, namely Xiao Yanyan and Princess Bohai. Ye Lu Xian almost died in a coup when he was a child. Since then, he has been in poor health and should not have so much energy to take concubinage. Yeluxian reigned for fourteen years, and ZSZSZSZ basically took care of the later government affairs for him. As for the Bohai Princess who once gave birth to his daughter, Liao history does not record it.
