With so much experience in design, how do you create a system to prevent children from getting lost, and what methods are there to find them if they do get lost? Please, sir...

Where have all the lost children gone? That’s the problem; if no one wants these children, then why would anyone go stealing them? 1. For organ trading, one can refer to the South Korean movie “Uncle” ； 2. Some buyers want children as a way to continue the family line. If organ donation or the use of artificial organs were highly developed, and buying such organs were also considered a criminal offense, then there would be much less of this problem, right? There’s now a website called something like “Baby Home” or similar, and there are many volunteers across the country. Anyone whose parent, sibling, or relative has gone missing, or who believes they have been abducted, can go to the police and provide a DNA sample. In this database, automatic matching and tracking are carried out; once a match is found, further DNA testing is conducted to confirm the identity, and thus the person is located. In Shenzhen, from time to time, the media reports on families that have been separated for many years being reunited. Actually, I think a harmless, implantable positioning system should be beneficial for preventing children from getting lost. Wearable devices such as children’s watches are basically useless in cases of child abduction, as everything on the child’s person is usually replaced at that point.

The guarantor must have lost it; other accidents cannot be ruled out! You can consider using GPS; just watch a movie and you’ll know: lol

Use a child watch quickly – it has GPS tracking and can also make calls.

How to prevent children from getting lost and what ways are there to find them if they do get lost! Are you the spokesperson for human traffickers?

The guardians should do more – take action themselves. They need to watch over them during their childhood; once those children are able to fly on their own, it will be impossible to keep an eye on them anymore

The topic raised by the original poster is excellent and worth exploring. In my opinion, regarding this issue, until technology reaches a certain level, it depends on our guardians to make more efforts. If technology reaches a certain level, such as the implantation of chips in the brain that allow for global positioning, I think that’s something one would only see in science fiction movies; it doesn’t make much sense to discuss it now. It’s okay to imagine such things as a form of boasting. Well, let’s get back to the topic at hand. Guardianship over children is absolutely crucial, which requires us to invest more time and effort. Prevent children from going out or staying alone, ensuring seamless supervision. This is a systems engineering effort that requires the participation of schools and society in addition to parents.
