Some monkeys are playing in a tree near a lake. They are having a good time. Suddenly a little monkeys cries, “Look at the moon has dropped into the water!” “Get it out, hurry!” says the old monkey.
The little monkey hangs(悬挂) from the tree by his tail. Then each monkey hangs from the other by his legs.
At last they get to the water, but still they cannot scoop(用勺舀) up the moon. Another little monkey finds half a gourd(葫芦) to scoop up the moon. Aha! He gets the moon in the gourd.
At that time all the monkey come for the moon. But the gourd drops and the moon is broken. The monkeys are very sorry. But they look up, they find the moon is still high up in the sky, shining brightly.
