Water from the Yangtze River, tea from the top of Mengshan Mountain. Mengding Mountain is located in Mingshan District of Ya'an City and has been famous for its tea since ancient times. It is one of the best tea producing areas in China. The Ganlu and Huangya produced there are of high quality and have been famous for a long time. Mingshan tea producing area has good tea sources and a large producing area, but the publicity and promotion are poor. It is not as famous as other tea producing areas. It feels like tea is in the deep mountains and unknown to people.
