First, it reflects China's attitude towards human nature education. This is a common practice of parents in China. They are ashamed to talk about this with their children, and they don't want others to talk about it with their children. They just habitually prevaricate that you will know when you grow up, because they don't know how to talk to children at all, and they don't want to talk to children.
Perhaps in their view, children are at an innocent and romantic age. You are actually polluting your child's innocent nature by telling him about sex education at this time, so parents are very reluctant to tell him about it.
It is also for this reason that parents sued the teacher, who felt that the teacher should not tell the child the posture of this piece so early.
Second, parents overreacted, and the teacher's approach was actually not wrong. But obviously, everyone thinks that this parent has overreacted, thinking that the child is nine years old, and it is actually no problem to tell this knowledge to the child. Moreover, the teacher also said that it was because other teachers were pregnant and the child always asked questions, so he told this knowledge to the child.
In fact, there is nothing wrong with the teacher's starting point, and when the child reaches this age, it is actually the age to accept this knowledge, but the parents think it is inappropriate.
It can be seen that the teacher is not wrong in this matter, but parents are ashamed to talk about this with their children, so parents think it is inappropriate for the teacher to tell the children about this matter. But judging from the reaction of netizens, it is obvious that they are more supportive of the teacher's approach. After all, if you don't teach your children, they may not know how to protect themselves. If things happen in the future, it will be too late for parents to regret. After all, there are too many things that children don't understand about this violation.
