Beijing, November 5 (Youth.cn) - Photo taken at Kuankuoshui nature reserve in Zunyi, Guizhou Province on November 3rd. The nature reserve is located in the north of Suiyang County. It is the only old-growth forest in the same latitude on the earth. With 85.42% forest coverage rate, it is also known as “green lung of Guizhou” or “green diamond”. In late autumn, leaves appear different colors. It is the best time in a year to visit this scenic spot. One may see clouds and fog envelop the mountains and valleys that covered with colorful leaves. It is a great pleasure to feel its nature charm. Photo/VCG
