What does it mean to engrave a sound on an old object?

It is estimated that it is a copperplate print from Chen Yinsheng, but it has not been identified yet, so the possibility of counterfeiting cannot be ruled out. Because Chen's reputation is abroad, there are a lot of fakes behind him.

Chen Yinsheng was a famous copperplate printmaker in the late Qing Dynasty and the Republic of China. From the late Qing Dynasty to the Republic of China, Zhang, Zhang, and Zhang were the most famous artists of the Beijing School, and they were called the Three Masters of Bronze Carving. Of these three people, Chen Yinsheng has achieved the greatest success. His name is Lin Bing, a native of Shuntian (now Beijing), a metallurgical scholar, a general practitioner, and he is good at calligraphy and painting. Zhicheng Deng's "Gu Dong Notes" said: "Those who set up professional ink cartridges in Shi Jing factory are the first to promote Wan Li Zhai, and the lettering began in Chen Yinsheng scholar." Chen Yinsheng's bronze carving art is exquisite, no matter he is a flower, bird, fish and insect, or a landscape figure, but his most important achievement is his calligraphy works, which are excellent in words, lines, grass and seals. It can be said that he is careful with his words and flowing freely. Representative works include Preface to Lanting in regular script, Teacher's Watch and so on.
