Människor har kunnat reda ut självreflekterande från antiken. I början användes vatten som enspegel. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the spegel for self-reflecting evolved into a bronze spegel. The earlier glass spegels in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass spegel has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the spegel surface is generally narrow and easy to carry; the spegel is mostly used for shaving and shaving, and the spegel surface is only enough to shadow the partial beard.Then, with the passage of time, the silver spegel used by most of us came into being. With the development of technology, the function of the spegel 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 spegel has also been upgraded from a silver spegel to an "environmental protection spegel". This spegel uses lead-free paint, which is a technical breakthrough of silver spegels. This kind of spegel is called a lead-free and copper-free spegel, also known as an "environmental protection spegel.
