Su Mian and Bai Jinxi were not the same person in Ding Mo's " Beauty Stuffing ". This book was a very good novel. It told a story about time travel and forensic identification. The protagonist, Su Mian, was an excellent female forensic doctor. In the process of solving a mystery, she traveled through time and space to the past and became a young woman, Bai Jinxi. The story was exciting, the characters were vivid, and the plot was full of ups and downs. It was worth watching. As for whether the male and female protagonists were physically and mentally clean, it depended on the specific situation. In the novel, Su Mian and Bai Jinxi's background was very complicated. They had experienced many difficulties and pain, but they also gradually grew and changed through continuous efforts. Although they may have some impure behavior under certain circumstances, they were able to pay for their mistakes and start their lives again in the end. Therefore, I believe that the male and female protagonists should be clean both physically and mentally.
