Introduction by Xinye Qingxia: Yi Yin plowed the fields with Xin and enjoyed the way of Yao and Shun. During the Xia and Shang Dynasties, the daughter of the You Xin family married as the concubine of Tang of Shang Dynasty. Yi Yin went with You Xin family as a dowry minister, so as to taste the soup and promote the king's way. "Poetry of the Ming Dynasty" proves that Qiaochuan was the country of the Xin family during the Shang and Zhou dynasties, and the "Qingxia of Xinye" reflects the natural landscape of "Yiyin Farming" at that time.
