Corresponding to the lowercase of the number, use Chinese characters homophonic with the number to indicate the amount again to prevent tampering!
Capitalized numbers are a unique way of writing numbers in East Asia. Use Chinese characters with the same pronunciation as numbers instead of numbers to prevent them from being tampered with. According to textual research, capitalized numbers were first invented by Wu Zetian and later improved by Zhu Yuanzhang.
The use of quantity in characters and numbers 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.
At the beginning of the Daming regime, it was stipulated that every year all ministries, prefectures and counties in China should send accountants to the household department to report the income and expenditure accounts and the amount of money and grain in local finance. The figures between governments at all levels and with the Ministry of Housing must be completely consistent. If there is any mistake, it will be returned and reported again. Because the place is far from the capital, in order to save time and avoid the pain of business trip, all localities have brought blank account books with official seals. If it is returned, please fill in the corrections at any time. Moreover, because the blank account book is covered with sewing seals, it cannot be used for other purposes, and the household administration department has not intervened.
