The rectangular handwritten Song Zhuo She inkstone has a larger surface and a slightly smaller bottom, arranged in an inverted trapezoidal shape, with a deeper inkstone pool. On the left wall of the inkstone, there is an inscription in clerical script: "Ye Ye from the Dragon Pond, standing in the center of the Zhai, has been writing for thousands of years, using grass and mystery. Wanli Renchen is like the inscription of the master Wang Tingne." The double seal script inscription reads "Secretary of the Huancui Zhai Map."
