A long time ago in China there were two friendsone who played the harp skilfully and one who listen skillfully.
When the one played or sang about a mountainthe other would say: "I can see the mountain before us."
When the one played about waterthe listener would exclaim: "Here is the running stream!"
But the listener fell sick and died. The first friend cut the strings of his harp and never played again. Since that time the cutting of harp strings has always been a sign of intimate friendship.
