The Shennongjia Nature Reserve is home to the rare golden monkeys, which have lived for many years on the verge of extinction since they were first spotted in Shennongjia in the 1960s. The amount of golden monkeys in the nature reserve has doubled since the 1980s because of better environmental protection. [Photo/Xinhua]
