I recommend you to read 'Secret Affairs of Chengqian'. This is a novel about the palace struggles and political power struggles during the reign of Emperor Qianlong. The male protagonist, Qianlong, traveled to ancient times and became an emperor. There were many concubines in the harem, and the power struggle inside and outside the palace was complicated. The plot of the entire novel was compact and the rhythm was fast. The plot of the palace and political struggles was very exciting and thrilling. I hope you like my recommendation.😗
