Who invented fonts one, two, three, four, five, six, seven, eight, nine and ninety?

Counting with capital figures, according to research, capital figures were first invented by Wu Zetian and later improved by Zhu Yuanzhang.

The article "The Origin of Capitalized Numbers" published by Mr. Hou Jialiang in Chewing WordsNo. 12, 2004 says: "In order to crack down on corruption, Zhu Yuanzhang also enacted severe laws to punish economic crimes, adopted technical preventive measures in financial management and implemented some effective measures.

One of the most important points is to change the Chinese characters' one, two, three, four, five, six, seven, eight, nine, ten, hundred, thousand' into capitals, and use' one, two, three, four, five, land, seven, eight, nine, ten, thousand'. "That is to say, counting with capital figures originated from the Ming emperor Zhu Yuanzhang.

Capitalized numbers in extended data are a unique digital writing method in China. Use Chinese characters with the same pronunciation as numbers instead of numbers to prevent them from being tampered with.

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.
