Guidong County in Chenzhou is the highest county in Hunan Province, with a forest coverage rate of 82 percent. It enjoys the reputation of "natural air conditioning oxygen bar city and national ecological demonstration county". In the early autumn, due to the unique geographical environment, there are clouds floating around the villages in the whole county in the early morning, sometimes showing a corner of the village, sometimes showing a few houses, and sometimes showing green hills, which has the feeling of "dream home, fairyland on earth".
