Perched at the source of the Xin'an River, one of China's least-polluted waterways, Youlong village boasts the perfect environment for a tea garden.

The 1,200-year-old village in Huangshan city's Xiuning county in Anhui province - long known for its lush scenery - is a center for the cultivation of organic tea.

One of China's first organic tea planters, Fang Guoqiang, president of Huangshan Xin'anyuan Organic Tea Development, has played a key role in the village's transformation over the past 20 years.
