'Knife painting' discovered in city of Dunhua

Metal scrapers, paint brushes, a piece of foam, a wood chip, pieces of small cloth.

Such modest materials might look like junk, but in the eyes of some painters in Northeast China's Jilin province, especially in a small city of Dunhua, they are precious.

Seldom used in other paintings, the tools add or reduce colors, creating sepia paintings that look so real it seems a landscape appears in front of your eyes.
