Extended data:
There is a hot spring, which is the oldest hot spring in Kansai, Japan. It is a convalescent facility built by Buddhist monks in the 8th century. Located in the northern part of Kobe, Hyogo Prefecture, Youmachi has a long history and is known as the "hinterland of Kobe". It is one of the three famous Japanese springs (Xialu Hot Spring and Cao Jin Hot Spring).
The water quality of hot springs in Ma You is rich in minerals. The spring water contains iron salt springs with twice the concentration of seawater, which can be divided into rust-red "Jin Quan" and colorless transparent carbonate springs "Silver Springs". Ma You Hot Spring Area is an elegant hot spring hotel concentration.
② The beauty of big prism hot spring lies in that the color of the lake changes with the seasons. In spring, the lake changes from green to bright orange. This is because microorganisms such as algae and bacteria containing pigments live in mineral-rich water, and the ratio of chlorophyll to carotenoids in their bodies changes with the seasons, so hot spring water also presents different colors.
In summer, the chlorophyll content is relatively low, showing orange, red or yellow. But in winter, due to insufficient light, these microorganisms will produce more chlorophyll to inhibit the color of carotenoids, so the water they see is dark green.
(3) Baotu spring water gushes from underground limestone caves, with the maximum water inflow of 240,000 cubic meters per day and the exposed elevation of 26.49 meters. The water is crystal clear, the water quality is mellow and sweet, and the bacterial content is extremely low, which meets the national drinking water standard after testing.
The spring water is kept at around 18 degrees Celsius all the year round. In severe winter, water vapor curls like a thin layer of smoke. On the one hand, the spring pool is deep and sparkling, and on the other hand, it is a pavilion and a painting boat. Carving beams and painting buildings constitute a wonderful fairyland on earth, which the locals call "clouds and vapours".
According to the data, the New Zealand-Rotorua volcano hot spring ranks tenth in the list of the top ten beauty hot springs in the world.

"Rotorua" means "Crater Lake" in Maori, which is why this small island in the middle of North Island of New Zealand is famous all over the world.
Thousands of years ago, Rotorua volcano erupted, forming a unique natural landscape in the volcanic zone of an island. In Rotorua, there are boiling mud lakes, hot springs, lakes and pastures. Here you can enjoy all kinds of fun brought by nature and marvel at the magic of nature.
⑤ The majestic Alps behind Evian Town are the source of Evian water, which comes from the melting snow in the hinterland of Alps and Shan Yu. After 15 years of natural filtration and mineralization of glacial sand, Evian water was formed. It is this kind of spring water that makes French girls who soak in hot springs spotless and radiant, and also makes French hot springs win the reputation of "Queen of Hot Spring City".
