The use of capital figures began in the Ming Dynasty. Zhu Yuanzhang issued a decree because of a major corruption case "Guo Huan case" at that time, which clearly required that the number of bookkeeping should be changed from "one, two, three, four, five, six, seven, eight, nine, ten, ten and one hundred thousand" to "one, two, three, four, five, seven and nine". Later, "Mo" and "Qian" were rewritten as "Bai and Qian", which have been used ever since.
