Yes Hui Boss Jewelry Fair, which was broadcast live in Tik Tok, attached a jewelry appraisal certificate, which recorded the origin, material and expert's appraisal signature of the jewelry, as well as the watermark of the merchant. It's true. Tik Tok, a short video social software with musical creativity, was hatched by ByteDance. The software was launched on September 20, 2006. It is a short video community platform suitable for all ages. Users can choose songs, shoot music works and form their own works through this software.
