There's an ancient story about the fearless general Zhang Fei of the Three Kingdoms Period. Once he was bragging about his courage, and his interlocutor said: "I know something that you will definitely be afraid of. Come closer and I'll tell you."
有這麼一個古老的故事，在民間傳了千年：天不怕、地不怕的三國猛將張飛，一回與人誇口自己什麼都不怕，對方說：「有一樣東西你一定害怕，附耳過來。」
