In ancient times, bronze mirrors even had a status symbol. The use of mirrors can be traced back to thousands of years ago, probably in the Shang and Zhou Dynasties, when bronze mirrors existed. Because of technical problems, bronze mirrors were very rare at that time, so they were all sacrifices, and their status was high. Later, with the gradual improvement of technology, it was no longer so difficult to make bronze mirrors, and everyone could afford them. At this time, bronze mirrors can also show different identities of different classes. Because the front of the bronze mirror is the same, there is no difference, but there are plenty of places to work hard on the back, so for those ancient senior classes, they carved patterns on the back of the bronze mirror, which can show their status and have a symbol of majesty. Therefore, when exhibited in the museum, only the patterns on the back can be seen, so they are all for everyone to see, and the patterns on the back can also be used as clues for speculation, such as when the bronze mirror was produced, who was the previous owner, and so on.
Bronze mirrors also have metaphysics. Because from the perspective of geomantic omen, besides being used by people, bronze mirrors can also influence geomantic omen, which is called geomantic omen mirror. Although geomantic omen is superstitious and its credibility is not high, it is a tradition after all and deserves respect. Sometimes what science can't explain can only be explained by Feng Shui. Therefore, according to Feng Shui, it is not a good sign to point the mirror at people. Nature is the best behind.
The bronze mirror is an antique, and the front is like that. Because after so many years, the bronze mirrors are almost corroded, and it is difficult for the mirror in front to show things, which is not as useful as the mirror in the back.
