Okay kiddo, do you know what a rich kid is? Someone who has a lot of money and gets to buy whatever they want. Well, in China there is a word for these kinds of kids, it's called "fuerdai". That's a special name for kids who are born into really rich families and have lots of money and don't have to worry about things like working or studying hard to get a good job.
These fuerdai kids get to wear fancy clothes, live in big houses, and go on luxury vacations. They can buy expensive phones, cars, and anything else they want. They don't have to worry about the price, because their parents will always pay for it.
Some people think that fuerdai kids are spoiled and don't appreciate how lucky they are. But, it's also important to remember that these kids didn't choose to be born into rich families. It's just how they were born.
So, to sum it up, fuerdai kids are kids who are born into rich families and have lots of money and can buy whatever they want.
