Although the water surface of the five lakes in Wudalianchi is separated by a bank formed by lava, the water flows through the caves at the bottom of the lake and is still connected by one vein. What is particularly surprising is that the colors of the bottom of the five lakes are different because of the different substances and water quality. In particular, the fish naturally produced here is the local people's favorite food.

"Mineral spring fish, it only lives in cold water and mineral water, so we call this fish mineral spring fish locally. This is a cold-water fish. We sometimes eat other fish with earthy smell, but our fish live in cold water. It grows slowly and its meat is tender. And it was salvaged from the lake and stewed with metasilicate mineral water from five lotus ponds. The local name is river water stewed river fish, so it is original. "

The five ponds in Wudalianchi have their own characteristics: the first pond has lotus flowers, the second pond is a natural fish farm, the third pond has the largest water surface and the best scenery, and the fourth pond and the fifth pond have patches of reed wetlands, which are ideal habitats for wild waterfowl. On the bank of Erchi, I saw some local people, stringing the caught fish, baking them and selling them to tourists.
