Introduction by Lin Hai Tingtao: 40 kilometers to the north from Mordaoga National Forest Park, nearly 100,000 hectares of dense cold temperate bright coniferous primeval forest - Xing'an larch primeval forest - stretches. This is by far the best preserved and largest natural deciduous virgin forest landscape in the Greater Khingan Mountains. At the "Linhai Tingtao" scenic spot, the "Tingtao" boulder sits on the edge of the forest, showing the original wild charm; the Russian-style red-roofed wooden house is half submerged in the dense forest, releasing the elegant poem of "a little red in the green bush" Affection. Walking along the spongy forest grass path, looking up at the ancient trees standing on the wall, the tree crowns are connected with each other as green as a canopy, the blue sky becomes variegated, and the sunlight is only a few golden strands; looking down at the forest vegetation, wild flowers and green shrubs are intertwined with each other, and colorful butterflies Moths flutter like shuttles. A few birds chirping and deer chirping occasionally break through the silence of the mountain forest, and a few fallen trees that have been uprooted by the wind sadly tell the vicissitudes of nature.
