I am also the parent of a generation of arrogant little leaders. I am really grateful to see the change of my child in just a few days. It's also a deep touch for me. I have made clear the goal and direction of educating children. In terms of price, I think it's very worthwhile. The shortcomings and advantages of children are subtle. Don't wait until children have shortcomings in education and life to attract attention and then complain. Might as well give it to them earlier.
