Rong Baozhai's woodcut watermarking technology integrates engraving, printing, cutting and other technologies, and has been praised by Mr. Lu Xun.
After liberation, under the care of the Party and the government, Rong Baozhai's technology of copying printed matter reached its peak, which was very similar to the original, enough to confuse the fake with the real.
Rong Baozhai's masterpieces "The Map of Wen Yuan" and "The Riverside Scene at Qingming Festival" have been exhibited in many countries, attracting the admiration of countless famous artists and enjoying a high reputation internationally.
When Mr. Qi Baishi, a master of Chinese painting, was alive, he could hardly tell which one was his original and which one was copied.
