Introduction to the red birch forest: The red birch forest is more than ten meters wide, ranging from tens of meters, and about 1 kilometer long. There are almost the same color of tall birch trees on both sides of the Hexi Highway, all of which are more than a hundred years old. The red birch forest is full of towering ancient trees, either curved or straight; in the dense places, the vines are entangled with kudzu, making it impossible for cattle and horses to move. Under the shrubs, strawberries, marlin, and mushrooms are everywhere, and the river flows around the forest, as if you have entered a fairy tale world.
