参考译文
Mengding Tea
Mengding Tea, a traditional green tea for the Han (China’s main ethnic group) with a long history, is produced in Mengshan Mountain across Mingshan County and Ya’an County in Sichuan Province. It requires an average annual temperature of 14.5℃ and an average annual rainfall from 2000 to 2200mm. Mist and clouds contribute to lower amounts of direct sunshine and more diffusion, which contribute to the formation of nitrogen content in tea leaves. The Mengding Tea enjoys the fame of being "xian cha" for its health benefits to the spleen, stomach and longevity.
