What's the mystery of Qingyu Spring Well?
There is a pool of cold mineral water in Chongqing Hot Spring Park. When the water in the spring pool is clear and transparent, it indicates that the weather will clear up. When the pool water becomes turbid and bubbles a lot, it indicates that there will be heavy rain or heavy rain. The observation data for many years show that the water color change of this spring pool is very accurate in forecasting the weather.

There are also such springs near Sujia Village, Haiyang Town, lingchuan county, Guangxi. When the spring is clear, the weather is fine and it won't rain for a day. When milky water like rice soup flows out of the spring, it will rain within 3 days. The amount of mud in spring can also explain the size of rain. On rainy days, if the spring water begins to clear, the weather will clear up. Locals can know the weather changes according to the daily changes of spring water.
On the east side of the new site in Qingfeng Township, Guigang City, Guangxi Province, there is a pond formed by spring water, with a surface area of about 3 mu and several springs with a daily flow of about 30,000 tons at the bottom of the pond. The water in the pool is clear and overflowing all the year round. Strangely, before the heavy rain comes, the water in this spring pool will turn pale red every 12 hour. According to the determination, the pool water contains more than 20 kinds of trace elements such as strontium and radon. However, it is still a mystery why the pool water will turn red before the rainy day.
