Pen: amount conversion, the amount of Arabic numerals is converted into a traditional Chinese form, such as: (￥1011)-> (one thousand and one pick up one yuan) Output

The reason for collecting this question is that I have done it before, but it is very troublesome to implement it. This time, it is easy to understand what others wrote.

We can see from a PDF that the source is not pasted =. =
