During the Jinghe period of the Dajing Dynasty, the emperor was obsessed with civil affairs and neglected the control of the harem. Queen Shen Weilan took charge of Fengyin in the name of "virtue", but in fact she was well versed in the art of checks and balances. After the Mid-Autumn Palace Banquet, the emperor ordered a performance to be held in Changyin Pavilion in the Imperial Garden on the first and fifteenth day of each month, and ordered the concubines to attend the performance. A secret palace battle under the guise of "watching a performance" began.
