"Book of Rites·Liyun": "The river produces pictures of horses". . Heluo's words were first seen in "Shangshu·Gu Ming" and also in "The Analects of Confucius·Zihan". "Shang Shu·Gu Ming": "Dayu, Yiyu, celestial sphere, and river map are in the east preface." "Guanzi·Xiaochen": "In the past, the recipients of orders were Dragon Turtle False, He Chutu, Luo Chu Shu, and Di Chu Cheng. Huang, there is no such thing as Sanxiang today.
