I recommend "The Pure Dream of Being a Concubine" to you. It's an ancient romance novel. The main story was about the female protagonist Yuyao who traveled to the Qing Dynasty and wanted to live a leisurely life. However, she was sent to the harem of Emperor Qianlong by her family as a concubine, so she wanted to become the concubine of Emperor Yongzheng to be more comfortable. However, when she entered the palace, she found that Yongzheng was very different from what she thought. He was even forced to become the Empress Dowager. I hope you will like this novel. Muah ~
