By far, Dong has cultivated over 20 craftsmen on the art, and has built up a production base on Filigree Mosaic artwork in Zunhua of north China's Hebei Province, where he has also trained nearly 100 farmers.

Joining hands with Beijing Cultural Development Foundation, Dong started a project in 2023 on cultivating new-generation Filigree Mosaic talents across Beijing, Tianjin and Hebei. "It's lonely and tough in persisting the art," said Dong, "My love for it has encouraged me all along the way." In his view, to pass down the craft, artists should come up with products that cater to modern aesthetics and people's daily needs.
