Introduction to Daheiqing: Daheiqing is 3850 meters above sea level and is the area with the most abundant plants in the Jiaozi Mountain Scenic Area. Here, you can see tall fir forests and large yellow rhododendron forests. This place is a "treasure house of medicinal materials" in Jiaozi Mountain. Not only does it grow green velvet, one of the eight famous flowers in Yunnan, but you can also find precious medicinal materials such as snow-capped wormwood, snow tea, rhubarb, rhodiola, and caowu. In other parts of the country, fir forests are usually found at altitudes above 3,300 meters, while Jiaozi Mountain can be seen at altitudes above 2,700 meters. In addition, the large area of yellow-backed oak forest in the Jiaozi Mountain Reserve is unique in central Yunnan and even rare in the entire southwestern region.
