You travel with your family, you accidentally lose your family, and your mobile phone is not in your hand. This is the person you want to help. What will you do?

In this case, it is very simple to ask for help from people around you. You are separated from your family and your mobile phone is not at hand. This situation must be very anxious. The person you ask for will have his own judgment when he sees your expression, so you don't need to worry. You can directly ask for help from people around you, of course, you can't rule out rejection, but I think it doesn't matter. One person can't do it and there will always be another person.
