People in ancient China thought the pig's big head and ears were a symbol of good luck. Pigs also stood for wealth, as humans used every part of the pig. Piggy banks are a symbol of this. Most children have a piggy bank that they can use to save money.
There are some famous sayings about pigs. For example, "when pigs fly" is used to say that you do not think something will happen. If someone eats a lot of food all at once, we say they "pig out".
