Ang mga tao ay nakapag-uri-uri ng pagmumuni-muni mula sa mga sinaunang panahon. Sa simula, ginamit ang tubig bilang asalamin. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the salamin for self-reflecting evolved into a bronze salamin. The earlier glass salamins in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass salamin has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the salamin surface is generally narrow and easy to carry; the salamin is mostly used for shaving and shaving, and the salamin surface is only enough to shadow the partial beard.Then, with the passage of time, the silver salamin used by most of us came into being. With the development of technology, the function of the salamin 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 salamin has also been upgraded from a silver salamin to an "environmental protection salamin". This salamin uses lead-free paint, which is a technical breakthrough of silver salamins. This kind of salamin is called a lead-free and copper-free salamin, also known as an "environmental protection salamin.
