Introduction to Lianhuan Lake: Lianhuan Lake Waterfowl Hunting Ground is located in Duerbot Mongolian Autonomous County in the southwest of Heilongjiang Province, with a total area of 58,000 hectares. Standing on the shore of the lake and looking around, the chain lake, which is composed of 18 lakes of different shapes and sizes, is like a string of silver links, with beads interlocking and connected. This is how the three words "Lianlian Lake" came into being.
