What does it mean to have a bear?

Laugh at yourself or others. A lot of jokes can be used to laugh at yourself or others. A joke comes from a scholar who gave birth to three sons. The three sons grew up, but there was nothing they could do. The scholar had to let them go to the mountains to collect firewood. In the evening, all three sons came back. The scholar asked his wife, "Who of the three fights more firewood?" The wife said, "When I am old, I have no knowledge at all, but jokes are a burden." It is generally used by later generations to laugh at themselves or ridicule others.
