One thing you must tell your children, you may not even know

Have you noticed that there is a string of numbers on every street light pole in the city? In fact, this string of numbers is very useful. It is what is often called the street light pole positioning alarm.

Mothers must tell their children that no matter what the reason, if they are lost from their parents and are alone, they should find a way to quickly find the nearest lamppost, and then find a public telephone booth. They can dial 110 without a card, and then clearly and accurately report the number on the nearest lamppost to the police and wait where they are.

The same goes for adults. When calling the police but cannot clearly tell the location, the easiest way is to report the number of the lamppost.
