What happens if the birthday paper is lost?

If you lose it, you lose it. Few people are interested in birthdays now. Unless it falls into the hands of someone who has a deep hatred with you, he will use it to harm you, but not many people know how to use it to harm others. I don't think there is any problem. There are also ways to crack it, but it can't be said here, and it's very troublesome. If it's okay in seven days, it's okay.
