Evaluation of Xerox inkstone

Xerox inkstone has always been favored by emperors, generals and literati. The title written by Song Huizong is "The mountain is high and the moon is small, and the water comes out". Su Shi, a great calligrapher in the Song Dynasty, once treasured two tile-shaped inkstones with the inscription: "Golden Sound Yu Pei." In Song Dynasty, Mi Fei's Mo Shi, Gao Sisun's Mo Zhu and Si Ku Quan Shu all recorded Xerox Mo. Due to various reasons, the carving skills of Xerox inkstone have been lost for hundreds of years and reappeared in the early 1980s.
