Disguise was a common fictional skill in martial arts novels. There was no conclusive historical evidence to prove that it really existed. However, ancient China did have a lot of techniques and practices related to makeup and changing one's appearance. These techniques were called "cosmetics" and "beauty techniques". In ancient China, people used various herbs, spices, fats, and other natural materials to make cosmetics such as lipstick, eyeshadow, perfume, shampoo, and so on. These cosmetics could not only improve one's appearance but also enhance one's self-confidence and charm. In addition, the beauty techniques of ancient China were also very developed. People can improve their skin condition by washing their faces, applying skincare products, massaging, acupuncture, and other methods to achieve a cosmetic effect. At the same time, people also enhanced their image and temperament through changes in hairstyles, clothing, and accessories. Although disguising is a fictional skill, ancient Chinese makeup and beauty techniques are real. They are still widely used not only in ancient times but also in China and other Asian countries today.
