Story:
During the Spring and Autumn period, Confucius was traveling and studying in the State of Qi. One day, while strolling in the outskirts, he heard a delightful melody. He followed the sound and found an old man playing the "Shao" music in the woods.
The melodious music completely dispelled Confucius's inner worries. For several months thereafter, Confucius remained completely absorbed in this music, to the point where he did not even notice the taste of meat.
