In the seventh year of Xining in the Northern Song Dynasty, during the wave of political reform, Beiyuan Imperial Tea Garden's "Dragon Group Wins the Snow" became a hot potato - this top-quality tribute tea made from three-pointed tongue buds had to be sent to Bianjing in seven days to offer sacrifices. Chen Mo, a junior official in the Fuzhou Transportation Department, was sent here because he disobeyed his superiors. He was a tea farmer, and he saw tribute tea squeezing people's fat. During the transportation, he saw tea farmers falling off cliffs and boatmen drowning. In the old and new party struggles and government and business exploitation, he gradually awakened from being a "little official who followed the rules" and wanted to use his humble life to expose the evils of the tribute tea system so that the "bloody" dragon group could defeat the snow and no longer become a tool for cannibalism.
