Parents should educate their children. If we get separated, if you don't have parents around you, when you need help, you should seek uniformed personnel in subway stations or public places.
In daily life, parents should educate their children and seek some help skills. When children know that they have lost their way, they will remember their parents' teachings and ask for help, so they will not panic. At this time, the child will not be blind and helpless, nor will he cry. He knows there will be a way to help him solve it. He will find a way. Therefore, if the child remembers what her parents taught her, she will be very sensible to go to the uniformed security guard in the subway station and ask for help. In fact, at this time, the child's mentality and practice also determine a test of parents' usual education.
