Black rice mashe is a traditional seasonal snack of Han nationality in southern China. In the past, it was called the eighth day of the fourth lunar month as the birthday of cattle. According to legend, on this day, beetles descended to earth, so there was a saying that plowing cattle worked hard for others. This statement is especially valued by Taizhou people in Zhejiang.
