Blind boxes have become popular in China these days.When you buy one，you never know exactly what you're going to find inside.Some people think this is the reason that makes them fun to buy.
   However，blind boxes can encourage risky behavior.If you really want the toy from a blind box，you might not get it in the first box that you buy.So you buy another box，hoping that you will get the toy you want.Then you buy another，and another.Pretty soon，you've spent all your money.That sounds like gambling（賭博） to people.
   It's okay to buy a blind box once in a while.But we have to be careful not to get addicted（上癮的） to the feeling of gambling that blind boxes provide.Part of growing up is learning self-control.If you can stop yourself from spending all your pocket money on things like blind boxes，you will be better prepared to keep yourself away from risky behavior as an adult.
