This has brought a lot of convenience to the villagers nearby. Many villagers come here to wash clothes, fetch water and take a bath, and some tourists bring eggs, which will soon be cooked in the water.
Some netizens also said that in Huanghai Hot Spring Town, northeast of Dandong, Liaoning, the seawater hot spring at 75 degrees Celsius has a great experience from small to large, and it is guaranteed to be a real hot spring. It seems that this situation is normal in the local area, and it feels that the enjoyment of washing hot springs from childhood is not enjoyed by ordinary people.

Reasons for the formation of hot springs
The formation of hot springs can generally be divided into two types:
One is formed by magmatism in the crust, or accompanied by volcanic eruption.
In the dead volcanic terrain where volcanic activity has been active, the surface and underground uncooled magma raised by crustal plate movement will release a lot of heat energy continuously. Because of the heat concentration of this kind of heat source, as long as there are pores in the nearby water-bearing strata, they will not only be heated into high-temperature hot water, but also boil into steam, mostly sulfate springs.
The other is formed by the infiltration and circulation of surface water.
That is to say, rain drops to the surface, permeates downward, and penetrates into the aquifer in the earth's crust, forming groundwater (sandstone, conglomerate, volcanic rock, these good aquifers).
Groundwater is heated by geothermal energy below to become hot water, and deep hot water mostly contains gas, mainly carbon dioxide. When the temperature of hot water rises, if there is a dense impermeable rock above it to block the way, the pressure will be higher and higher, so that hot water and steam are in a high pressure state, and as long as there are cracks, they will rush up.
After the hot water rises, the closer it is to the surface, the pressure will gradually decrease. As the pressure gradually decreases, the gas contained in it will gradually expand, reducing the density of hot water, which is more conducive to the rise of hot water. The rising hot water circulates repeatedly with the pressure (hydrostatic pressure difference) generated by the density difference of the cold water that sinks and heats later, resulting in convection. When the resistance of the open fracture is small, hot water rises along the fracture and gushes out of the surface, so that hot water can rise endlessly and finally flow out of the surface to form hot springs.
With the topography of high mountains and deep valleys, the surface water at the bottom of the valley may be higher than that of high mountains, and the groundwater level is in the middle and lower levels. Therefore, the bottom of the deep valley may be the place with the largest hydrostatic pressure difference, and the possibility of hot water rising from the bottom is the greatest. Most hot springs appear on the river bed of the valley.
