In the fifth year of Tianshun in Ming Dynasty (146 1), the unified annals of Daming written by others made a textual research on Jiang's city harmony. Thirty-four volumes of Fengxiang Mansion Monument record: "Jiangshi City: south of Baoji County, south of it." "The Emperor's Century": My mother's surname is Gao, and a woman boarded it. She is a young princess, traveling in Huayang, touching the dragon head and giving birth to Emperor Yan, that's all. Jiang's city is now called Jiang Castle, with Yimen Castle in the south and Qingjiang River, a tributary of Weihe River in the west.

In the thirty-sixth year of Wanli in the Ming Dynasty (1608), the "Baoji County Records" contained: "(Jiang's city) was once passed on, and Zhou Jiang was born here". In the twenty-ninth year of Qing Qianlong (1764), the "Baoji County Records" contained: "Wulijiang Shicheng in the southeast of the county has an address in the southeast. There is a bath in the east, St. Jiuyan Spring. " . In the thirty-first year of Qing Qianlong, the records of Fengxiang Prefecture were published in three years: Jiangyuan Temple: Nanjiang City, Baoji County, and Shennong Temple: One in Dongguo County and One in Jiulongquan County. In the 23rd year of the Republic of China (1934), the Shaanxi Tongzhi Draft continued to analyze Li Daoyuan's Qi Shui, namely Jiang Shui. Among them, "Zhiyi" said: "Those who leave the capital Yangshan are also in the same water; Out of the Qinling Mountains, Jiang Shui also. Li didn't take the exam, so he moved the capital in the name of Qi Shuishui, which was a mistake. Today, Jiang Shui is in South (Baodi) County, and Zhongzheng City is in the south and east, so you can bathe in Sanjiu Eye Spring. " .

The ancient Yandi Shennong was born here. According to legend, Shennong was born in Mengyugou, Yangshan, with a cow head. After giving birth to the baby, his mother Jiang Yuan took a bath in Jiulongquan. After Emperor Yan bathed in Jiulong Spring, his horn disappeared and his talent became more intelligent. Later, he became the leader of the Chiang tribe. He is called the inventor of traditional medicine in China, because he tasted hundreds of herbs, discovered medicinal materials and taught people to treat diseases. At the same time, Emperor Yan taught people to make pottery and began to make mistakes. He lowered cattle and cultivated crops, which made the primitive times progress from gathering and hunting to agriculture. People respectfully call him "the god of agriculture", and the Jiang tribe headed by Yandi Shennong has lived here ever since.
