On the agricultural sacrifice at the end of one year, the disciples of Confucius all went to watch it. But Confucius didn't go. When they came back, Confucius asked them if they have had a great time. A disciple replied, "Everyone seemed to be mad, but I don't know why they act like this." Confucius said, "The people have worked for the whole year and got this one day of entertainment. Even Duke Wen and Wu of Zhou dynasty could not make it if they always work and never get relaxed. To strike the balance between tension and relaxation is a way of governance of Duke Wen and Wu." Later in exile in other states, Confucius had also served as a priest for several times.
