the emperor girl was hot

Are you referring to Joan Chen who played the Empress Dowager? The real empress dowager Longyu was the one who abdicated for the child emperor Pu-Yi back in 1912. She died at the age of 45 in 1913. The movie has her referring to Pu-Yi as her son. She was married to the Guangxu emperor and did not have any children and acted as regent for Pu-Yi. Pu-Yi was her nephew, not her son.
