The earliest attractions found and developed by tourism in Lishui County, Shandong Province are located more than ten kilometers south of Lishui County. There is a special tourist road. The traffic is very convenient. If you travel by car, you can navigate directly. The earliest time was called four gates. Later, it was renamed the underground fluorescent lake. Okay, from the firefly cave. In fact, fireflies are fake, made with small bulbs, it feels good. I don't recommend everyone to go.
