Introduction to Ertai Forest Farm: Ertai was named after the military platform and post station in the Qing Dynasty. The grasslands and wooden houses here complement each other, making it the best place for tourists to rest. Going south from Ertai, the mountains gradually get lower and the valley mouths gradually open up. On both sides of the road, you can see spruce trees, strange poplars and willows, apricots and wild fruits, and the eyes are full of fresh green.
