The population of the autonomous county is made up mainly of Miao and Tujia people, and Yushan Gansubing (crispy cake) is their must-eat dish during the Mid-Autumn Festival. The cake has a history of more than 200 years, dating back to the Qing Dynasty (1644-1911). Using flour, malt sugar, sesame and osmanthus flower, the cake is sweet, aromatic and crispy. The traditional delicacy was included in Chongqing's intangible cultural heritage list in 2009.
