It is also because this hairpin has gone through many complicated processes and edification when it was made. As we all know, in ancient times, making a hairpin often went through many processes and took a lot of time to polish it. This has caused the hair clasp to have great endurance when it is polished, which will make it very shiny and look like a new hair clasp after so many years. Even if it has experienced so much wind, rain and sun, it will not experience such discoloration or other States.
Some people will have such a question that this hairpin has been around for 4,000 years. Will it be oxidized if it is taken out rashly? In fact, this phenomenon does not exist, because for a hair clasp with so many years of history, if it is to be taken out, many scientists need to carry out a series of research results before it can be taken out completely. It is precisely because this hairpin spent a lot of technology and technical level when it was made, reaching an unparalleled level, so it can be well preserved.
Another point is that this hairpin has very good value when it is made, and the materials used are genuine. We are skeptical about some real gold and silver on the market now, because there are some other things mixed in it. But in ancient times, this phenomenon did not exist at all, because the ancient princes and nobles were very eager for this aspect, so the things paid to them must be very valuable, and there would be no such phenomenon. This is also its real material, so it can be well preserved until now.
