The hot springs of Junlan Hot Spring Hotel cover an area of 20 acres, with beautiful scenery and 27 hot spring pools with their own characteristics. The original soup is taken directly from the underground. The spring water is clear and transparent when it comes out of the well, but because the water is rich in divalent iron ions, it turns reddish brown as soon as it encounters air, so it is known as "golden soup" and is a very rare natural resource. The hot spring water temperature is maintained at 42 degrees Celsius all year round, does not change with the seasons, and the water quality is fine. The content of metasilicic acid, free carbon dioxide, and metaboric acid in the water reaches the mineral water concentration in the national hot mineral water quality standard. The water also contains iodine, barium, bromine and other trace elements that are beneficial to the human body. It has the characteristics of being soft and smooth after bathing without being tight, and is a real heaven-sent spring.
