There are 14 volcanoes in Wudalianchi, and the volcanic eruption forms a pool connected by five streams, so it is named Wudalianchi, three pools in the middle, and the largest water. Bailong Lake (three pools) is an important "geological lake", the west bank of the lake area is a new period of volcanic lava landform, the east bank is an ancient sedimentary landform, the two sides through the hundreds of millions of years of time tunnel, the scenery is different, can be described as "one lake and two scenery". "Mountain reflection" is a must for three pools. Whenever the summer is 8 o'clock in the morning and 4 o'clock in the evening, the lake is still shadowing the blue, and the 14 volcanoes in the distance are reflected in the lake, hidden and more than enough, like a mirage, so there is a poem praise day: "Five pools are vast and green, like a clear mirror for nine days, the light boat is slowly blue waves far away, Fourteen mountain eyes hang.
