In China's mathematics, there are "three forms" originated from Zhouyi, among which the Great Liu Ren is the first one, and other mathematicians praise it as the best of the three forms. Judging from many related records in the Spring and Autumn Annals of Wu Yue, Yuejueshu and Biography of Qiuci, Liuren appeared later than Zhouyi. But not later than the late spring and autumn. So far, many Liu Ren disks have been unearthed in China. According to archaeological research, most of them belong to the Han Dynasty. This shows that Liu Ren was popular in the Han Dynasty.
