The Historical Origin of Chinese Numeral Capitalization
Digital capitalization began in the Ming Dynasty. Zhu Yuanzhang issued a decree because of a major corruption case "Guo Huan case" at that time, in which it was clearly required that the number of bookkeeping must be "one, two, three, four, five, six, seven, eight, nine, ten, ten, ten and thousand".
Change it to traditional Chinese characters such as "one, two, three, four, five, land, seven, eight, nine, pick up, hundred (strange), thousand (money)" to increase the difficulty of altering the account books. Later, "Mo" and "Qian" were rewritten as "Bai and Qian", which have been used ever since.
