Masyarakat wis bisa ngatasi refleksi dhiri wiwit jaman biyen. Wiwitane, banyu digunakake minangka apangilon. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the pangilon for self-reflecting evolved into a bronze pangilon. The earlier glass pangilons in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass pangilon has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the pangilon surface is generally narrow and easy to carry; the pangilon is mostly used for shaving and shaving, and the pangilon surface is only enough to shadow the partial beard.Then, with the passage of time, the silver pangilon used by most of us came into being. With the development of technology, the function of the pangilon is only self-reflection, it is more intelligent and more humane. More functional, such as: anti-fog, watch time, measure temperature, watch TV, etc. The material of the pangilon has also been upgraded from a silver pangilon to an "environmental protection pangilon".
