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.
