Story:
Once upon a time, there was a man who sold medicine for foot calluses in the market. He hung a signboard that read "For Imperial Use" outside his shop.
People ridiculed him for his dishonesty. When the emperor learned of this, he sent someone to summon the man and had him thrown into prison.
He was later released due to a general amnesty and returned home. He resumed his old business, but this time, he added four characters, "曾经宣唤" (once summoned by the emperor), to his signboard to attract customers.
