《太平广记·卷八十二·异人二》
老翁说： 我从小就学习吹笛子，老了仍没有倦怠。像您所用的这支笛子，不是我敢于知道的，王孙如以为不是这样，应当让我为您试一试。 
臾曰： 吾少而习焉，老犹未倦，如君所有，非吾敢知，王孙以为不然，当为一试。 
The old man said: “I have been learning to play the flute since I was a child and never felt tired of it even when I became old. A flute like the one you have, I don't deserve to know about it. If your Highness thinks this is not the case, please let me try it for you.”
