Ni Bin, male, is a British royal jewelry appraiser, jewelry appraiser and jewelry designer, a post-80s entrepreneur, the initiator and founder of Red Shopkeeper Jewelry, a pioneer and pioneer in China's jewelry e-commerce industry, and a cutting-edge fashion O2O jewelry industry.

When Baidu just launched the second-hand encyclopedia project, a person in charge of the second-hand encyclopedia saw Mr. Ni Bin's video about jade jewelry and found him, hoping that Ni Bin could provide the second-hand video about jewelry. Mr. Ni Bin always hoped that the jade industry could have a unified standard as soon as possible, so he agreed to Baidu's request.

So far, Teacher Ni Bin has recorded more than 100 videos for Baidu Second-hand Encyclopedia, covering more than 300 pieces of jewelry and jade, and basically recorded all the second videos of jade jewelry. Mr. Ni Bin said frankly that it is impossible to unify the industry standards in one second just by a video that understands encyclopedia, but with the help of the power of the Internet, the standards can be unified as soon as possible. Mr. Ni Bin and the brand he founded will also make continuous efforts to formulate jade standards, hoping to spread jade culture and China's oriental thought as soon as possible.
