Con người đã có thể tự phản ánh từ thời cổ đại. Vào thời kỳ đầu, nước được sử dụng như mộtgương. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the gương for self-reflecting evolved into a bronze gương. The earlier glass gươngs in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass gương has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the gương surface is generally narrow and easy to carry; the gương is mostly used for shaving and shaving, and the gương surface is only enough to shadow the partial beard.Then, with the passage of time, the silver gương used by most of us came into being. With the development of technology, the function of the gương 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 gương has also been upgraded from a silver gương to an "environmental protection gương". This gương uses lead-free paint, which is a technical breakthrough of silver gươngs. This kind of gương is called a lead-free and copper-free gương, also known as an "environmental protection gương.
