In addition to the famous gas mineral water in Beiquan, there are also large volcanic eruptions "Shilong Platform" and the lake where Erlong Spring water converges. Of course, spring water is a must-drink. It is recommended to take a small bottle to drink, but only two or three hours. Maybe I have psychological preparation in advance, so the taste of the water is okay, especially on a hot day, this breathy and cool spring water is quite comfortable to drink. There is now a pavilion on the spring eye, I can't see it, the water is coming out of one faucet. Locals or people who have a recuperation card can come in for free to get water. Tickets are now 25 yuan, if you buy a map, it costs 5 yuan.
