There are five diamond appraisal institutions in Shanghai.
Where 1, 2,5 are national certification bodies.
1. is the unified OTC certificate designated by Shanghai, which is the certificate you saw in Chow Tai Fook. However, I don't go to work on weekends. I need a card from one to five o'clock,10am to 4pm.
2. It is an institution with strict online uploading and biased actual appraisal results, which mainly supplements certificates for old shops such as Lao Fengxiang.
5. It is a year-round appraisal institution, but because students often practice, the appraisal level is not stable, and it is not bad as a re-examination institution.
In addition: the above addresses are all headquarters, and there are appraisal stations in Chenghuang Temple, and the personnel are basically the same as the headquarters. Pay attention to their working hours and don't run in vain. You can go to the East China Institute of Technology Appraisal Station on the second floor of Huangcheng Jewelry, or the light industry on the first floor of Laofengxiang, which belongs to the national certificate and can be used for reference.
