Xiaobai's suggestion is to learn GIC (the textbook is the British version) and compare the basics (the certificate course is a little more complicated). If the landlord wants to inherit his father's business in the future, he can take GIC's jewelry store manager training course to facilitate management.

Guangzhou Automobile is a national treasure association certificate, which is not as authoritative as GIC in the market.

NGTC (in cooperation with the United States) If the landlord wants to engage in the diamond industry, he suggests learning NGTC. Both GIA's diamond course and HRD's diamond course are systematic and authoritative. At the same time, it also undertakes the training of CGC.

CGC is the national registrar. Personally, I don't want to specialize in appraisers. If I just want to know theoretical knowledge and practical skills, I don't need to study. The pass rate is 30% ... It's so frustrating = =
