Historical origins of capitalization of Chinese numerals

Capitalizing numbers began in the Ming Dynasty. Zhu Yuanzhang issued a decree because of the "Guo Huan Case", a major corruption case at that time, which clearly required that the figures recorded in the accounts must be recorded by“一、二、三、四、五、六、七、八、九、十、百、千”改为“壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、佰（陌）、仟（阡）”and other complex Chinese characters to make it more difficult to alter the account books. Later, "Mo" and "阡" were rewritten as "Hundred、thousand" and are still used today.。

The origin of numbers
The earliest tools used by humans for counting were fingers and toes, but they could only represent numbers within 20. When the number was large, most primitive people used pebbles to count. Gradually, people invented methods of tying knots to keep count, or carving numbers on animal skins, trees, and stones. In ancient China, small sticks made of wood, bamboo or bones were used to keep count, which were called calculation chips. These counting methods and counting symbols slowly transformed into the earliest numerical symbols (digits). Today, countries around the world use Arabic numerals as their standard numbers.
