Please show me. Hou Shuiyan, is it true?

Excuse me, did you buy it at Taobao Tmall Whoo flagship store? I have been using Whoo's Tianqidan series. Whether I buy it locally in Korea, in a flagship store or in SF, there is only one ring on the bottle cap.

If you don't buy it at the official flagship store, you may have to feel it yourself.
