Although the distilled liquor of the Yuan Dynasty had Chinese names such as"hanjiu(sweat liquor)","shaojiu(burnt liquor)",and"zhongniujiu(heavy brewed liquor)",the once popular transliterations such as"Alakhai wine"have made the origin of Chinese distilled liquor a controversial issue in the international academic circle.This paper examines systematically the historical records of"hanjiu(sweat liquor)"and its preparation utensils,and combines relevant archaeological findings to explore the etymology of the name"hanjiu(sweat liquor)"and the origin of distillation equipment.It argues that the name"hanjiu(sweat liquor)"should originate from the historical allusion"han chu ru jiang(sweat flowing like thick soup)",and the vessel used to prepare"hanjiu(sweat liquor)"is actually a set of yan-styled distillation equipment including fu cauldrons and zeng steaming baskets.In particular,the correspondence between the"jiudang(liquor cauldron)"and ancient distillation apparatuses helps us to re-examine the origin and evolutionary process of Chinese distilled liquor and distillation equipment.
