The only legal and effective ginseng testing institution in China is Yanji City, Jilin Province, with the name of National Ginseng Product Quality Supervision and Inspection Center.

The name of the tester is Zhong Wei, and the testing certificates issued by the center are divided into yellow certificates and green certificates, in which the yellow certificate is wild ginseng and the green certificate is artificially planted and naturally grown ginseng under the forest.

The two people you mentioned have never heard of it, and they should belong to a fake appraisal agency.
