Introduction to Erlong Lake: There is an interesting story circulating in Erlong Lake. It is said that in the early days Erlong Lake was the place where water dripped all year round, so people called it Chengzi. There is a pearl on the chengzi, and there are two mountains next to it, which is called the two dragons playing with the pearl. As it continues all year round, puddles dozens of feet deep drip out. The deep pool water overflowed and was blocked by Pearl Mountain, forming a vast lake. The lake was surrounded by Erlong Mountain. Therefore, people call it Erlong Lake.
