Historically, Ma Su Lagu was sourdrang queen's personal maid. She should have served Xiaozhuang instead of Kangxi since she was a child. If she is Xiaozhuang's personal maid, she must be about the same age as Xiaozhuang, who is Kangxi's grandmother. Then Ma Su Lagu must be Kangxi's grandmother. How could she have feelings for Kangxi? This is inconsistent with history.
10. The death time of Gulu in Summala was wrong.
According to historical records, in the 26th year of Kangxi (1687), Xiaozhuang died of illness, while Aunt Summala died on the 7th day of September in the 44th year of Kangxi. The performance in the play is: "After Xiaozhuang died of illness, Summala menstruation died immediately", which is inconsistent with history.
