I just bought a bracelet and a bowl from there some time ago. The bracelet was tested as 4 9s and the bowl was 99. After I bought it, my family said that I was cheated, and I was less and less trusted by my family, so I went to our local quality inspection department for testing. As a result, the bracelet is not bad, and the bowl is 0.3. The staff of the quality inspection department said it was a good thing, and now everyone in the family is using it, so I asked them to give me some bowls as gifts. Really.
