Wudalianchi Town in the north of Heilongjiang Province is a scenic spot of Wudalianchi, a world geological park. There are fourteen volcanic cones and a series of shield volcanoes, which constitute a spectacular volcanic landscape. Volcanic cones and shield volcanoes were formed in the Quaternary Period, and the latest eruptions occurred in 1719.1721 A.D. in Old Montenegro and Burning Mountain. The lava from the eruption blocked the Shilongjiang River in four places, forming five volcanic barrier lakes and finally forming "Five Great Lianchi". In the scenic area, there are many kinds of lava landforms, such as rope-like, twist-like, wooden row-like and so on. Climbing the crater gives you a panoramic view of the scenic area. Appreciate the beautiful scenery of lakes and mountains, taste the taste of cold mineral springs. In spring, the lava is covered with lichen moss and the woods are full of colorful wild flowers; in summer, the green leaves are green, the lake is clear as a mirror, and the whole scenic area is clear in color; in late autumn, the poplar, birch and other plants here are rendered with large areas of red and golden yellow, which is the photographer's paradise. In winter, the snow is shining, and the scenery of the North Country is in full view.
