Story:
Once upon a time, there was a conceited scholar, mockingly referred to as "Dr. So-and-So."
He went to the market to buy a donkey.
According to the custom of the time, the buyer needed to write a contract for the seller. The "Dr." unrolled blank paper and began to write, producing thousands of characters, filling three entire sheets with irrelevant nonsense.
The donkey seller grew impatient and urged him to hurry up. He replied, "No hurry, I haven't even written the character for 'donkey' yet!"
