Related jokes about Su Dongpo's effect

There was a joke in ancient times: a monk was escorted to Fucheng by an emissary. While staying at the hotel, the monk got drunk, shaved his hair and ran away. When I woke up, I was surprised to find that one person was missing. Then I touched my bald head and turned surprise into joy: "Fortunately, the monk is still there." But then I wondered, "Where am I?"
