This capitalized digital Chinese character, although it looks a bit cumbersome, is different from traditional Chinese characters and is the capitalized form of the number one.

According to the existing historical records of China, the capital is 1234. These numerals first appeared in the Wu Zetian period.

But the writing at that time was slightly different from now. The person who really popularized uppercase numbers was Zhu Yuanzhang.

In the early years of the Ming Dynasty, people used to use lowercase numbers such as one, two and three handed down from ancient times.

One horizontal, two horizontal and three horizontal. This will be peaceful. It was not until later that a corrupt official took advantage of the loopholes in these figures to facilitate his own corruption that it attracted the attention of the court.

In the early Ming Dynasty, there was an official named Guo Huan. When he kept accounts, he changed the numbers with lowercase letters. As long as you add horizontal and vertical strokes, you can make a bigger number like 6790. Guo Huan used this principle to change the amount of silver in the imperial court, and put the extra part into his pocket, earning more than 7 million yuan for himself. His corruption was finally caught by Zhu Yuanzhang, because Zhu Yuanzhang was born in the folk and was persecuted by these corrupt officials in his childhood.

So after he became emperor, what he hated most was corrupt officials. Guo Huan executed tens of thousands of people in this corruption incident, which is the famous Guo Huan case in Ming Dynasty. In this case, the corrupt officials' operating methods also aroused Zhu Yuanzhang's deep thinking. In order to control the corrupt criminals from the source, he specially redesigned China's figures. The original one horizontal, two horizontal, three horizontal one, two and three are named lowercase counting characters.

I named one, two, three and ten words that I created as uppercase numerals, and now they are widely used in account books.
