Dong Ruijing, a Beijing native born in 1970, has been learning the art since he was 15. In 1988, he entered the Beijing Filigree Mosaic Factory and became an apprentice of three masters Yang Rui, Wu Kenan and Bai Jingyi. In 2006, he set up his own company to further develop the art.

For more than three decades, Dong and his apprentices have been dedicated to the innovation of the art, integrating it with other crafts such as lacquer carving and enamel art. Their products are now exported to markets like Japan, South Korea, Singapore and Malaysia.
