The reason why you can't find his information is because he is just a small shop, of course you can't. His name is imitation of the real Hong Kong brand "Liu Fu" jewelry. If you enter Liu Fu, there will be a lot of news and their official websites. He said that the national chain stores want you to trust him. Actually, it's nothing. Just because you bought a piece of jewelry in an unknown shop doesn't mean that what you bought is not good. You can call me if you need other help.
