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.
"Yuan" is the representative symbol of RMB. China began to issue paper currency RMB from 1948 12 1, with yuan as the unit and yuan as the Chinese phonetic alphabet.

Whether it is Arabic numerals (1, 2,3 ...) or so-called Chinese lowercase numerals (1, 2,3 ...), because the strokes are simple and easy to be altered and tampered with, the numbers on general documents and commercial financial bills should be capitalized in chinese numerals: one, two, three, four, five, six, seven.
For example, "3,564 yuan" is written as "3,000 Wu Bai and 64 yuan". These Chinese characters have existed for a long time, and they are used as capital figures and belong to borrowing. The complicated writing of this number was fully used as early as the Tang Dynasty, and then it was gradually standardized as a set of "uppercase numbers".
In today's modern society, it has become an "established" rule that bank drafts, current checks, practical invoices, contract agreements, account vouchers and other economic texts must be marked with capital figures. Moreover, with the development of high technology, financial institutions have developed and applied more complex anti-counterfeiting technologies, such as electronic payment passwords, intelligent fingerprint verification and specific identification, which further enhanced the confidentiality and security of state property and private funds.
