Once upon a time there was a very powerful old emperor in China. One day he made a solemn promise:
"I am going to conquer every one of my enemies. I will rid my kingdom of enemies." A few days later, one of his court officials was surprised to see him walking in his garden, arm in arm with some of his worst enemies. They were laughing and joking together.
"What is going on?" the courtier asked in surprise. "I thought you swore that you would wipe out all your enemies from your country?"
"I have actually wiped them out" the emperor answered. "I have changed them into friends."
