One: Parents set an example for their children. Parents are the best teachers for children. If they want their children to be excellent and sensible, they need to set a good example for them. Children are very clever and often imitate adults. If they love swearing and quarreling with others, how can they ask their children to be polite? Parents have to ask their children while doing it themselves. Under the influence of parents, the educated children will not be bad.
Two: Guide children to speak polite language. Being polite, a good habit can't be formed overnight. Need to take your time. Parents should consciously cultivate their children's polite language when they are young. When others help themselves, they should say thank you. Be sincere when asking others for help. After others thank themselves, we should also say you are welcome. Only by slowly letting children form such good habits can they become polite and loved by everyone.
Three: if you say something wrong, you should be educated in time. Some children swear when watching TV or playing with other children. This is imitation. Maybe they don't know what swearing means, but they just think it's fun. When parents find that their children have such behavior, they must educate their children in time to let them know that it is wrong.
Parental education is really good for children. Don't think it doesn't matter if the child is young. Habits are accumulated. When you find that there is something wrong with your child, you will definitely regret it later.
