The third concubine position in the harem was high but not higher than her spot in the Emperor's heart.
When the news of her sister, Duan Yi, becoming the Lord of Blue Moon became public, a few officials of the royal court, including the previous generation imperial teacher, requested the emperor to take back her status as they didn't want political power leaving the grasp of men and embracing women.
Many people rose in support of them as they wanted to keep the tradition of the empire as it is, one in which a woman cooks, take care of her man, and satisfies his needs while the man works and provides for the family.
As fate would have it, they were like herders playing the flute before a cow or dogs barking at a passerby as the emperor didn't listen to them and even picked up the ring leaders and threw them in jail as punishment for breaking public order.
He even killed those he found unpleasant to the eyes.
