Људи су могли да реше саморазмишљање од давнина. У почетку се вода користила каоогледало. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the огледало for self-reflecting evolved into a bronze огледало. The earlier glass огледалоs in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass огледало has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the огледало surface is generally narrow and easy to carry; the огледало is mostly used for shaving and shaving, and the огледало surface is only enough to shadow the partial beard.Then, with the passage of time, the silver огледало used by most of us came into being. With the development of technology, the function of the огледало 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 огледало has also been upgraded from a silver огледало to an "environmental protection огледало". This огледало uses lead-free paint, which is a technical breakthrough of silver огледалоs. This kind of огледало is called a lead-free and copper-free огледало, also known as an "environmental protection огледало.
