Zhao Mengfu's "Stele of Imperial Clothes Stored by the Great Yuan Dynasty" was erected in the second year of Yanyou of the Yuan Dynasty (1315). They were originally scattered in the fields in the northern suburbs of Zu'an Town. In 1962, they were moved and erected in the backyard of Chongyang Palace (today's Stele Hall). Zhao Shiyan wrote the essay, Zhao Mengfu wrote the elixir, and Li Meng wrote the seal script. This stele is built on a turtle base with a total height of 523 cm (the head height is 140 cm and the base height is 40 cm), the width is 138 cm, and the thickness is 35 cm. The seal script on Gui's forehead reads "The Monument of Imperial Clothes Stored by the Great Yuan Dynasty" in 2 lines and 8 characters.


The inscription on the stele has 34 lines in regular script, with 81 characters in the entire line. It records that Zong was inspired by a strange dream and bestowed imperial uniforms on Zhenren Sun. Zhao Mengfu was a famous calligrapher in the Yuan Dynasty, and together with Yan Zhenqing, Liu Gongquan, and Ouyang Xun, he was known as the "Four Masters" of regular script. This stele is a work of his youth, with beautiful and hearty calligraphy.
