Capitalized numbers are a unique way of writing numbers in China. 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 then improved by Zhu Yuanzhang, which has been in use ever since.
The capital figures of China should be written in block letters or running script, such as one (1), two (2), three, four (4), five (5), six (6), seven, eight, nine, ten, hundred, thousand, ten million, yuan, angle, minute and zero.
Do not use one, two (two), three, four, five, six, seven, eight, nine, ten, pronounce, send, or another (or 0) to fill in, and do not create simplified words. If numbers are written in traditional Chinese characters, such as 20, 60, 100 million, 10,000, and yuan, they should also be accepted.
Extended data:
"One, two, three, four, five, six, seven, eight, nine, ten, hundred and thousand" are full-time Chinese characters representing numbers, which are generally called lowercase numbers. Lowercase numbers are relatively simple and easy to be altered, so capital numbers "one, two, three, four, five, six, seven, eight, nine, ten and hundreds" should be used in documents and commercial bills.
"lowercase" refers to numbers, and "uppercase" only refers to numbers in bookkeeping. The two use different scenes, but not the relationship between simplified and traditional. Calligraphy works are not accounted for, and it is meaningless to use "capitalization" at will. "Capitalized numbers" originally had its own meaning, and later it was used to represent numbers. Some of their original meanings are still in use, while others have disappeared. Let's look at the original meaning of "capital" numbers.
