One piece 100 takes 50 or 3 working days if testing is needed. It is located in Little Huang Zhuang. I haven't been anywhere else. I don't know. 22 points don't need supervision. Those below 20 points will only be identified as true or false. If no specific data is given, there will be two more points, which is unnecessary. Is a 43-cent earring 43 cents for two diamonds or 43 cents for a pile of broken diamonds? Actually, I don't think it's necessary to test. Maybe you bought it very expensive, but the actual value is not high.
