As traditional tea processing techniques and their associated social practices in China were recently included on the UNESCO's Representative List of the Intangible Cultural Heritage of Humanity, the world is paying more attention to Chinese tea.
Southwest China's Sichuan province has the earliest history of tea growing in China, with one place in particular having great renown: Mengding Mountain in Ya'an. The average annual temperature there is 14.5 degrees, and the year-round mist and rain is beneficial to the forming of nitrogenous substances in tea leaves.
