In some western countries, many children do chores (家务) to get pocket money. They usually start to do this when they are ten years old.

School students have to do homework and study for tests.  They don’t have much free time on weekdays. They often do chores on weekends.

Young kids only do easy chores. So they don’t get much money. But that’s enough. Many of them only want to buy candy. And candy is cheap! They often help do the dishes, sweep the floor, or feed the pet cat or dog.

When they get older, they want to buy more and more things. They want things that are more expensive than candy. So they have to work harder! They often help their parents wash the family car, cut the grass, or cook meals.

Some jobs are a good way for kids to learn new things. For example, they can learn how to use a lawnmower ( 割草机) or how to cook. Of course, their parents help them at first.
