The rooster climbed onto a pile of sand and had a great time digging on it. He was busy trying to find some food, but finally he found a pearl. The rooster said: "Although this treasure is dazzling, it is of no use to me. It is better to find a grain of wheat and use it to fill its stomach. The chickens, ducks, sheep and pigs in our courtyard all like to eat wheat grains, so what do I need this pearl for? I don't need to wear this treasure, and I don't want to use it to dress myself up. Let people treat it as a treasure." After that, the rooster threw the pearl aside and continued to look for its grains of wheat.
