China's earliest classic of pharmacology, Shen Nong Ben Cao Jing, listed yam (Dioscorea opposita), rehmannia glutinosa, Achyranthes bidentata and chrysanthemum produced by Huaichuan as top grade. Later, from the outside to the inside, famous doctors and experts in past dynasties further discovered the excellent primitiveness of Sihuai drugs, and removed the rough and preserved the essence. So this theory has spread to this day and has become a brand.
Huaiyao is a pregnant man. Since the Zhou Dynasty, the "Xingqiu" was abandoned as Huai (located in the south of Tucheng Village, Dahongqiao Township, Wuzhi County), and this land was later called Huai, Huaiyi, Huaichuan, Qinhuai, Huaizhou, Huaimeng and Huaiqing.
Eight counties in Huaiqing Prefecture: Hanoi County (now divided into Qinyang City and County), Jiyuan County (now Jiyuan City), Mengxian County (now mengzhou city), Wenxian County, Wuzhi County, Xiuwu County, Wu Yuan County and County (the former county is now merged into Yuanyang County).

The origin of the name of Huaifu:
In the eleventh year of Dade (A.D. 1307), Yuan Chengzong died, and the court fought for power and profit, causing chaos in the ruling and opposition parties. Left-wing Prime Minister Ahudi conspired to make Bo Yuewu, Queen of Yuan Chengzong, king of the imperial court. Right Prime Minister Ha Sijas saw this situation, so he quickly sent someone to Huaining, Qinghai to meet Wang Haishan, and then to Huaizhou to meet Haishan's younger brother Li.
Because Huaizhou is close to the capital, Li Bada, the love of these days, has arrived in the capital. With the help of Sijas, the right prime minister, he killed Ahudai, the left prime minister, and became a prison army, temporarily acting as the emperor's agent to handle state affairs.
In May of the same year, Huaining Wang Haishan arrived in Beijing and proclaimed himself emperor, known as Yuan Wuzong in history. He changed his title to Zhida and made his younger brother Ai Yu Ba Li Libada the Crown Prince. Wuzong reigned for four years and died on the seventh day of the first month of 13 1. His younger brother, Ba Li Libada, became emperor, known as Yuan Renzong in history, and changed his country name to Huang Qing.
In the second year of Qing Dynasty (13 13), the Queen Mother issued a decree to rename Wang Huai Palace where Injong lived with his mother as Xinglong Temple (commonly known as Gao Tai Temple). In order to commemorate the achievements of Injong, Wang Huai Temple was built on both sides of Daguan Emperor Temple in the city, and Huaimeng Road was changed to Huaiqing Road with the word "Qing" in the year number "Huang Qing".
Decades later, the Ming Dynasty replaced the Yuan Dynasty and changed Huaiqing Road to Huaiqing House.
In the second year of the Republic of China (A.D. 19 13), the county was abandoned, and the old name "Huaiqing", which had been used for hundreds of years, was abolished, and the county name was changed to Qinyang County.
Since then, Huaiqing Prefecture has withdrawn from the historical stage as a place name.
