The earliest recorded mention of Yihongyuan dates back to the Han dynasty (206 BCE - 220 CE), in the mathematical treatise "Jiu Zhang Suan Shu." This text, one of the most influential mathematical works in Chinese history, presents various mathematical problems and solutions, including those related to geometry, algebra, and arithmetic. Yihongyuan is mentioned in the context of calculating areas and volumes of geometric shapes. The term "yihong" () implies unity, wholeness, and

During the Tang dynasty (618 - 907 CE), the concept of Yihongyuan gained further attention, as mathematicians and scholars began to explore its implications in more depth.
