Historical origin of Chinese uppercase numbers

Uppercase numbers began in the Ming Dynasty. Zhu Yuanzhang issued a decree because of a major corruption case at that time, the \"Guo Huan case\", which explicitly required that the numbers in accounts must be changed from \"一, 二, 三, 四, 五, 六, 七, 八, 九, 十, 百, 千\" to the complex Chinese characters \"壹, 贰, 叁, 肆, 伍, 陆, 柒, 捌, 玖, 拾, 佰 (陌), 仟 (阡)\" to increase the difficulty of altering account books. Later, \"陌\" and \"阡\" were rewritten as \"佰, 仟\" and have been used ever since.

Notes on Chinese uppercase RMB amounts
Chinese uppercase amount figures should be written in regular script or running script, such as 壹(壹), 贰(贰), 叁, 肆(肆), 伍(伍), 陆(陆), 柒, 捌, 玖, 拾, 佰, 仟, 万(万), 亿, 元, 角, 分, 零, 整(正), etc. Do not use 一, 二(两), 三, 四, 五, 六, 七, 八, 九, 十, 念, 毛, 另 (or 0), and do not create simplified characters. If traditional characters such as 贰, 陆, 亿, 万, 圓 are used in the amount figures, they should also be accepted.

1. If the Chinese uppercase amount stops at \"yuan\", the word \"整\" (or \"正\") should be written after \"yuan\". After \"jiao\", the word \"整\" (or \"正\") may be omitted. If the uppercase amount has \"fen\", do not write \"整\" (or \"正\") after \"fen\".

2. The Chinese uppercase amount should be preceded by the words \"人民币\". If the uppercase amount has \"fen\", do not write \"整\" (or \"正\") after \"fen\".

3. The Chinese uppercase amount should be preceded by the words \"人民币\". The uppercase amount should be written immediately after \"人民币\" without leaving any blank space. If the words \"人民币\" are not pre-printed before the uppercase amount, they should be added. In the uppercase amount column of bills and settlement documents, fixed words like \"仟, 佰, 拾, 万, 仟, 佰, 拾, 元, 角, 分\" should not be pre-printed.

4. When there is a \"0\" in the Arabic lowercase amount, the Chinese uppercase should be written according to the rules of the Chinese language, the composition of the amount, and the requirement to prevent alteration. Examples are as follows:
1· If there is a \"0\" in the middle of the Arabic number, write \"零\" in the Chinese uppercase. For example, ￥1409.50 should be written as 人民币壹仟肆佰零玖元伍角.
2· If there are several consecutive \"0\"s in the middle of the Arabic number, only one \"零\" needs to be written in the Chinese uppercase. For example, ￥6007.14 should be written as 人民币陆仟零柒元壹角肆分.
3· If the ten-thousands place and the units place of the Arabic amount are \"0\", or if there are several consecutive \"0\"s in the number and the ten-thousands and units places are also \"0\", but the thousands and jiao places are not \"0\", then you may write one \"零\" or omit it in the Chinese uppercase. For example, ￥1680.32 can be written as 人民币壹仟陆佰捌拾元零叁角贰分, or as 人民币壹仟陆佰捌拾元叁角贰分. Another example: ￥107000.53 can be written as 人民币壹拾万柒仟元零伍角叁分, or as 人民币壹拾万零柒仟元伍角叁分.
4· If the jiao place of the Arabic amount is \"0\" but the fen place is not \"0\", write \"零\" after \"yuan\" in the Chinese uppercase. For example, ￥16409.02 should be written as 人民币壹万陆仟肆佰零玖元零贰分; another example: ￥325.04 should be written as 人民币叁佰贰拾伍元零肆分.

Origin of numbers
The earliest tools used by humans for counting were fingers and toes, but they could only represent numbers within 20. When numbers were large, most primitive people used small stones to count. Gradually, people invented methods such as tying knots in ropes, or carving marks on animal skins, trees, or stones to record numbers. In ancient China, small sticks made of wood, bamboo, or bone were used for counting, called counting rods. These counting methods and symbols gradually evolved into the earliest number symbols (numerals). Today, countries around the world use Arabic numerals as standard numbers.
