Translation from 30 thousand to 10 thousand

I remember a joke called "From 30,000 to 10,000"

A rich man asked his teacher to teach his son to write, and wrote "one" first.

"Two" and "three", the rich man's son said that he learned to write, so he dismissed his husband. One day, the rich man had to write a letter to his friend for his son to write. His son painted crosswalks all over the paper from morning till night, saying, why does this friend have to be called "Wan"? It took him a long time to draw three thousand words.

I don't know if this is it.
