As 4L said, to find a seller in Taobao Mall, you need to register a business license and a trademark certificate, which is highly reliable. On the other hand, these shopping malls are well-known. I once bought it on Taobao twice, the first time I was looking for Lao Fengxiang. No problem, but it's very expensive. It feels good the second time. It's also from Shanghai. Chen Yi jewelry, go to Taobao to search for it yourself, hehe.
