This kind of parents are strict with them since childhood, and don't let them have time to play. Moreover, most of these parents stifle their children's nature and are very "cruel" to them. Just like the eagle, we all know that when the eagle teaches children to fly, it often takes them to a very, very high cliff and throws them directly from it. Because of this desire to survive, the young eagle learned to fly, and if he didn't learn, he would be killed alive.
In fact, I think this kind of education is tantamount to pushing children to a cliff. This kind of education is very likely to cause certain psychological pressure on children and suppress their personality. Even if they are trained to be children with good academic performance, they are likely to lose their foothold after a failure, which is also very unfavorable for children's future social development.
