Parents can tell their children a story, that is, a person obviously didn't use his ID card to get a bank loan, but when he applied for a mortgage, he found that his credit information was very poor and there were many credit card loans under his name. Under the inquiry, it turned out that the man's mother got the free washing powder with her ID card, and then the identity information was copied by the other party. Moreover, the other party also copied many copies of their ID cards, went to apply for credit cards and maxed out these credit cards. Through this short story, let the children understand that free is the most expensive sentence, which seems to be receiving washing powder, but in fact it is a card loan.
Many people are unprofitable and can't get up early, so it is impossible to do things that can't benefit them. Children may say that there is a lot of free knowledge on the Internet, and they can learn a lot through the Internet. But these free knowledge are relatively shallow. If you want to study deeply, you must pay. If you don't pay, you can only watch pirated ones, which will be more difficult and may lead you to some illegal websites, which will also bring some dangers. Parents can also tell their children that our love for you is free, but it is also the most expensive, because it is your responsibility and obligation to support your parents when you grow up.
It is not good for children to understand such abstruse things, which may make them feel very stressed, but it can also make them more sensible.
