It's a brand, a national registered trademark, and some people say it's (Golden) Health, Zhou (Da) Fu and Lao Feng (Xiang). A cottage brand, one word for each cottage. This is a small brand. Zhou Dasheng, who has worked for many years now, can't guarantee the gold content of thousands of gold. Do you think this will work? It's best to find several big brands. After all, it is very troublesome for individuals to re-examine their rights.

Usually, even if the gold content of this brand enterprise is slightly lower, it will not be too bad.

I hope I can help you.
