Extended data:

In the early years of the Ming Dynasty, a "major corruption case in Guo Huan" involving 12 senior officials and six assistant ministers used blank account books to make false accounts and embezzled money and grain by tampering with figures, with a total amount of more than 24 million stone (tons), almost equivalent to the total amount of autumn grain requisitioned in China at that time.

Zhu Yuanzhang was furious and ordered tens of thousands of accomplices, including Guo Huan, to be beheaded. At the same time, he made strict laws to punish economic crimes and took technical precautions in financial management-changing the numbers in Chinese characters into capital letters that are difficult to change.

That is, "one two three four five six seven eight nine 10000" was changed to "123456789 1000 money" and so on ("money" was later changed to "money" next to the singular), which was called the first capitalization of numbers in China history.
