Tangquanchi is named after a hot spring and is famous for its medical value. Hua Tuo, the legendary doctor of medicine, is known and used by people because he is known as the "divine spring". The hot spring was formed about 1 100 million years ago, which was formed by the nearly north-south Shangma fault formed in Yanshan period and its derived northeast fault. At present, there are three springs with 650 tons of sunrise water, the water quality is clear and clean, the water temperature is 56℃-58℃, and the spring water contains strontium, silver, titanium, boron, chromium, copper, lead and lead through spectral quantitative analysis. Using the thermodynamic effect and medicinal chemical action of hot springs, it has obvious curative effect on dermatosis, rheumatism, gastrointestinal diseases, nervous system, respiratory system, surgery and gynecological diseases, especially the cure rate of dermatosis and rheumatism is as high as 80%. Healthy people who often take a bath can also care for beauty, increase food and hypnotize, so they are called "medicine springs". As early as the Tang Dynasty, Li Jifu called it "warm soup" in Yuanhe County Records. Ming Jiajing's "Shangcheng County Records" records: "The hot spring, 30 kilometers southwest, flows out of the stone, which is blue in color and as hot as soup. People can cure scabies by bathing." Villagers gather in spring to form a "Tangkeng Diancheng", build a "Fan Jing Temple" on Leishan Mountain and a "Tangkeng Bridge" on Guanhe River. In the 25th year of Qing Qianlong (AD 1760), Emperor Qianlong visited Tangquanchi and wrote an inscription "Tangkeng". During Jiaqing period of Qing Dynasty, the government established the "Hot Spring Academy" here. After that, an official pool, a men's pool, a women's pool, a laundry pool and a warm water well will be built. Many literati and poets who touched guests in history have been here. Li Zhi, a great thinker and writer in the Ming Dynasty, and Wang You, a native of Qingyi, both wrote poems in Linquan, and wrote famous sentences such as "A thousand streams wash their hearts, enough in the hot spring palace" and "There are dark veins in Leishan that lead to hot springs, such as the muddy days in Huaqing".

When Liu Deng's army jumped thousands of miles into the Dabie Mountains, the soldiers were acclimatized and suffered from scabies. Liu and Deng, the leaders, heard that the hot springs were magical, so they sent troops to seize the Tangquanchi and let the soldiers bathe to cure diseases. As a result, the "plague chicken" became a "tiger" and shattered the enemy's crazy "encirclement and suppression". The washing of Tangquanchi laid the foundation for the establishment of Dabie Mountain base area and the successful liberation of Nanjing, so some people called Tangquanchi "the first spring of China revolution".
