In the discussion about the origin of the word SPA, there is a word that runs through it, that is "hydrotherapy", which reflects the important role of water in the ancient treatment field and early European SPA culture. In many parts of Europe, the word spa still maintains its strong historical connection and is strictly used in institutions related to SPA. In the English-speaking area of Europe and some other parts of the world, the meaning of the word SPA has become more extensive.

The essential oil in the water comes from the soaking of thousands of flowers and plants in the upper reaches of the local mountains. People simulate similar environment and water quality construction, which is the modern "SPA". SPA not only provides facial, hand and foot beauty, but also various courses such as health care, body shaping and weight loss.

Several types of hydrotherapy:

1. Day spa: Due to the limited space and dense population, urban spas are usually located in famous restaurants and shopping centers. There is also the pattern of independent stores, and the course of treatment is not as long as the SPA in the resort center. Metropolitan SPA has its own courses to cope with the tense urban rhythm. For example, many beauty clubs can provide modern women with services such as beauty, body shaping, makeup, color consultation, SPA and health care.

2. beauty SPA: most of these spas are mainly female customer service, and many spas in China are transformed from beauty salons.
