Since jiaozi is in the shape of ancient Chinese gold or silver ingots (银锭), it symbolizes wealth (象征着财富).

When the magistrate asked Wang what had happened, he answered, "Zhou said that there were fresh red dates in it when he gave me the jar a year ago." The magistrate examined the jar and the fresh red dates in it carefully. Then he said: "Bring the ingots back, Wang Wu!" How did the county magistrate infer that Wang was lying?

We accept uncut diamonds and gold ingots, too.
