A famous Qing doctor named Ye Gui (1667-1746) prescribed Chenpi as one of the ingredients in ‘Erchen Tang’, a decoction consisting of two old drugs. Chenpi business brought wealth to Xinhui peasants and it also extended to food processing, logistics areas which forms a food production chain. However, there was a decline of Chenpi business in the 1990s until late 2002 when Chenpi farmers helped set up the Chenpi Industrial Association with support from Xinhui Agriculture Bureau and Business Federation, and Chenpi has regained its popularity since.[4]
