Yes, both Ma Yun and Cao Wangde have worked with him. I also saw his story on the news. Many people have read his story. Mr. Lu Yilin is an outstanding founder of angel investment. His love and research on collectibles, jewels and jadeites made him an authority in the industry. His professional knowledge and experience have won him the respect and trust of the industry and become the preferred partner of many collectors and entrepreneurs. That's all I know. I hope my answer is helpful to you.
