I recommend 'After Wearing Pure Clothes to Add Blessing'. This novel is about the love story of Concubine Dong E and Shunzhi. The protagonist Meng Guqing was reborn and returned to his previous life. He witnessed the poignant love between Concubine Dong E and Shunzhi. The story was full of hidden bitterness and touching, deeply attracting people's hearts. I hope you like my recommendation.
