A man lives in a small village. There is no market in his village. So he often walks for about half an hour to buy things in the town. One day, he goes to the big market to do some shopping. He spends about two hours walking around slowly in the market because there are many things. After getting all the things he needs, he gets out of the market. When he walks past a small store, he finds two boxes in it. Both of the two boxes are very beautiful and the man loves them at the first sight(第一眼). So he buys them happily.
Then he takes a taxi to get back home. But he doesn't know how to use the two boxes. He thinks for a long time and then decides to do something special. He puts all of his happiness in the yellow box and all of his unhappiness in the black box. He thinks it's funny to do that.
A few days later, the yellow box becomes very heavy, but the black box is still light(轻的). He doesn't know why. He decides to open the two boxes to find the reasons. He opens the yellow box and finds nothing. Then he opens the black box and finds a big hole(洞) at the bottom(底部).
Then he smiles to himself and says, "Happiness is for me, let sadness go."
