If others know about you, will your birthday hurt you? It is out of the question. Because birthdays are just a time period. In other words, there are 12 hours in a day. There are two hours in an hour. There are many people born in two hours. In other words, there will be many people with the same eight characters. Then if he is picky, he will also be picky about many people. The price is too high for anyone to do it.
So if others only know your birthday, don't know your name, don't have your personal clothes, or have something contaminated with DNA, there is no way to hurt you.
There is another key point, you should also have enough interest, especially in this way, the cost is very large, and it may be at the expense of life. So no one will want to hurt you, don't worry.
