The seal inscriptions "Yu Shan Di Yi Shi Jian" relates this seal to the "Yushan school" in Chinese seal carving history. There are two Yushan schools in China, one was represented by Li Gao 【林皋】 (1657-?), and the other by Zhao Shi 【趙石, alias Guni 古泥】 （1874 - 1933）, both active in Changshu of Jiangsu province but differ in styles.
The side inscriptions bear the name of "Yun Zhai" (Cloud studio), which suggests the relationship with one of the Yushan School seal carver, Pang Shilong [龐士龍] (1899 - 1987), whose alias is Yunzhai.
