It is above 3 meters in diameter and 1.5 meters deep. There are dozens of big springs of vapor with a temperature of 94℃ at the mouths of the springs, where you can steam food. There was a legend that once upon a time, an ox drank salty water of spring and dropped into it owing to its carefulness. When the shepherd boy turned back with villagers, the ox has already become beef. The two Chinese characters "热海" (Hot Sea) were carved on the stone standing 30 meters away from "the big boiling pot". There are some bathrooms and steam beds for people to take a steam bath or receive medical treatment
