Адамдар ежелгі уақыттан бастап өзін-өзі көрсететін нәрселерді сұрыптай алды. Басында су а ретінде қолданылғанайна. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the айна for self-reflecting evolved into a bronze айна. The earlier glass айнаs in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass айна has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the айна surface is generally narrow and easy to carry; the айна is mostly used for shaving and shaving, and the айна surface is only enough to shadow the partial beard.Then, with the passage of time, the silver айна used by most of us came into being. With the development of technology, the function of the айна 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 айна has also been upgraded from a silver айна to an "environmental protection айна". This айна uses lead-free paint, which is a technical breakthrough of silver айнаs. This kind of айна is called a lead-free and copper-free айна, also known as an "environmental protection айна.
