Introduction to the virgin forest: In the Narisu Scenic Area of Chuoyuan National Forest Park, a lush, leafy, bright coniferous primeval forest landscape in the cold temperate zone reaching into the clouds is preserved. After the double predatory logging by Tsarist Russia and Japanese invaders, the only remaining virgin forest is about a hundred years old. It has undulating mountains, towering ancient trees, rich vegetation and dense streams. Larix grows densely, with straight and tall trunks, with an average height of about 25 meters and an average diameter of more than 36 centimeters. There are lush green trees, colorful flowers, refreshing fruits, and crystal-white snow. It presents a unique northern scenery all year round.
