Wang Feng is the "China Painting and Calligraphy Liquid", commonly known as the patent inventor of Bai Mo, and the founder of "China Painting and Calligraphy Liquid" (Bai Mo). Twenty years ago, inspired by Mr. Xie, the inventor of batik technology and black ink (the founder of Yidege), Wang Feng was inspired to study "Bai Mo". He boldly imagined that by painting "Bai Mo" on raw rice paper without any traces of painting, dry rice paper became cooked rice paper. He observed under a microscope and came to the conclusion that the difference between raw rice paper and cooked rice paper is due to the different density of the paper. If a layer of material is coated on raw rice paper, the density of the paper can be increased and the effect of cooked rice paper can be produced. After 20 years of repeated experiments in Wang Feng, "Bai Mo" came out successfully. A new painting and calligraphy material commonly known as "Bai Mo"-China Painting and Calligraphy Liquid. It is understood that the use of raw and cooked Chinese paintings and the use of white powder are two major problems. Wang Feng's invention of "Bai Mo" has obtained the national patent, and the product has been pushed to the national market by a century-old factory, Beijing Yidege. The appearance of "Bai Mo" is a revolution of China's painting and calligraphy materials and techniques. "Bai Mo" has solved two major problems that have plagued the artistic creation of calligraphy and painting for a long time, namely, the use of a piece of paper and natural blank space, which can make the artistic creation of calligraphy and painting produce unexpected and peculiar effects. As can be seen from the above text, the "white" in "Bai Mo" refers to the "white powder" used in Chinese painting.
