Huoshan County in east China's Anhui Province is an important producing area of dendrobium nobile, a valuable Chinese herbal medicine found in the rocks.
Thanks to the improving ecological environment, local people have created wealth in planting the herbal medicine.
The industry has brought thousands of people into employment, with a total output value of 3.5 billion yuan (around 520 million U.S. dollars).
