Over thousands of years, the springs flow all day long, freed from the change of season. They were used by local people about 6,000 years ago. From the Zhou Dynasty to the Tang Dynasty, emperors ordered bath pools built here. Gradually, they became the imperial bath pools. It was an honor for a court official to take a bath here. The “Fine Sunset-Bathed Pavilion” stands on the ancient source of the spring water, which was discovered 3,000 years ago. The springs have a flow if 113 tons an hour and a constant temperature of 43℃. The spring water is rich in minerals. An analysis shows that the water contains silicon dioxide, fluorine, and other minerals, which makes it suitable for bathing and the treatment of quite a few diseases such as dermatitis, rheumatism, arthritis etc. Its value in medical treatment was discovered some 2,000 years ago, roughly in the Qin Dynasty. It was recorded in many books in different dynasties. In present bath area in the Huaqing Pool, the pools inherit their names from those in the Tang Dynasty. They provide a fine place for guests to relax and appreciate the high-quality of spring water.

Among the 2700-odd hot springs in China, Huaqing Pool hot springs top the list for the water-quality and the touching love story of Tang Emperor Xuan Zong and his favorite Yang Guifei. The springs have a constant temperature of 43℃. The water contains silicon dioxide, fluorine, and other minerals, which makes it suitable for bathing and the treatment of quite a few diseases such as rheumatism, arthritis etc. Therefore, the spa had been a tourist destination for many emperors. For example, for ten years from 745 A.D. to 755 A.D., Emperor Xuanzong would lead Yang Guifei and her sisters to Huaquing Palace to spend his winter days. They would stay there from October of the lunar calendar to the next spring. As Bai Juyi, a famous Tang Dynasty poet, once wrote a few lines to describe how Yang Guifei took her bath: It was early spring. They bathed her in the Lotus Flower Pool, which warmed and smoothed the creamy-tinted crystal of her skin, and, because of her languor, a maid was lifting her when first the Emperor noticed her and chose her for his bride. Thus Huaqing Pool's hot springs became famous and were entitled “The Oriental First Springs” ranking with the Thermae of Caracalla in ancient Rome and the Bath Hot Springs in Britain.
