It is very important to train children's language skills. It is very important for children to lay a good foundation during their growth. Let children speak standard words and Mandarin, and let them dare to express their thoughts and opinions. Some children are afraid to speak and are not good at speaking since childhood. After a long time, they have developed a closed personality, the so-called introverted personality. On the one hand, children will be laughed at by their classmates because of their nonstandard speech and dare not speak. On the other hand, they lack self-confidence in themselves and dare not express their views on anything, which limits their children's growth space, which is unfavorable and unfair to their development. Once this happens, it's hard to change it.
