The crow thirsty 口渴的乌鸦
A crow feels very thirsty. He flies to a water pot, but the pot is almost empty. He tries his best but in vain. Then he tries to push the pot over so that the water can flow from the pot. But he cannot move the pot. Just then, he thinks up a better method: one by one he puts into the pot. With each stone（increases）, the water level gradually increases. At last, the crow drinks the water and satisfies his thirsty.
This story means: wisdom is beyond strength.
