There are no birds calling each other in the deep forest." The tall trees with dense branches block out the sun, and they are majestic. The tall and majestic red pine kings stand up to the sky; the century-old poplars with different expressions on the giant tree island stand towering; the white birch forest is stacked with mountains and hills; the hanging trees have different expressions. The roots hang on the earth; the roots of the Golden Toad Spear tree are as thick as giant claws coiled around the Golden Toad stone, and the rocks are surrounded by pines and rocks, interpreting the century-old relationship between pines and rocks. Being in the forest oxygen bar, immersed in the vast forest sea, looking up at the tall trees, breathing the fresh air, enjoying the natural fragrance of the trees, listening to the sounds of water and birds, relaxing the mind, it can be said that heaven and man are one. Known as the "Castle in the Sky", the tree houses are built on top of mountain peaks and suspended in the woods. It is the best place to listen to the pine waves, view the forest and sea, and taste pine tea. The Northeast Anti-Union Secret Camp Site is the most complete preserved Anti-Union Secret Camp site in Northeast China. It is an important revolutionary base for the Northeast Anti-Japanese War and a famous patriotic education base in Heilongjiang Province. In 2008, the Sixth Anti-Japanese Army headquarters, clothing factory, machinery repair shop, military and political cadre school and other sites were rebuilt at a 1:1 ratio. It reproduces the arduous fighting life of the Anti-Japanese War fighters at that time. On this basis, the Northeast Anti-Japanese War film and television base was built, and many film and television works with Northeast Anti-Japanese War themes such as "On the Songhua River" were shot here. This is a revolutionary traditional education base and a key red tourism scenic spot. While feeling nature, people can step on the anti-Union road again, drink anti-Union water again, accept revolutionary traditional education in a subtle way, and inspire patriotism.
