I want to ask English. Parents who know can talk about it? Urgent! ! !

My son took part in the oral English contest held in the city and was eliminated in the first round of the semi-finals. What the first child said was really good, not like what a third-grade elementary school child said at all. Parents discuss that it is a foreign teacher's class to learn English. After I came back, I signed up for an audition class for my children online. Pure pronunciation, I guided the child to talk more and gave her 40 lessons. Now I have attended about 32 classes, and the progress is obvious.
