Kunshi, also known as Kunshan Stone (Figure 2.24), is named after Yufeng Mountain in Kunshan, Jiangsu Province, and is also called "Three Famous Stones in Jiangsu" with Taihu Stone and Yuhua Stone. Kunshi, which is produced in Yufeng Mountain, is unusual, reticulate and veined, and its wood is scarce, so it is called Qiao Shi, also known as Linglong Stone.
