     Long ago, there was an interesting man called Effendi (阿凡提), He was very humorous. One day

he had a joke with the Prime Minister (宰相). He said that the Minister would die the next day. Really

the next day, the Minister fell off the horse and died. When the king learned this, he got angry and sent

his men to catch Effendi at once. When Effendi was in front of the King, the king shouted angrily, “Effendi, since (既然) you know when my Minister would die, you must know the date of your own death. Say it

out, or you will die today.” Effendi looked at the king for a while, he answered, “But how can I know?

I’ll die two days earlier than you.” Because the king was afraid if he killed Effendi, he himself would die

after that. He thought he must keep Effendi alive as long as he could, so he let Effendi go.
