When looking for a seller in Taobao Mall, you must register your business license and trademark certificate, which is highly credible. 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.
