What would you do if you heard a child yelling in a public place?

If I hear a naughty child yelling in a public place, I will definitely tell the parent of that naughty child and ask him to control his child and not let him act like this in public. Hu Xiaoming, I think if you can’t communicate with the naughty child, then you can only communicate with the naughty child’s parents. If you really can’t communicate, then you can only seek help from the local management staff
