Why not bring out the bullying kids and the school to talk about it?
That's why I don't expect other children's children to come forward and point out, or even expect the school to detect bullying incidents in school in the first place and take appropriate measures. These are the follow-up options.
We still have to deal with and solve everything on our own. There is a first suspected incident in any school bullying incident, and parents must intervene in time from the source, which can effectively avoid the further development of the school bullying incident.
Tell me about my family.
Since my child was growing up, I have always instilled in him the idea that no matter what happens at school, no matter whose fault it is, he can talk to his parents when he comes back. Especially after entering primary school, it is obvious that children will encounter some suspected bullying incidents at school. Some can even elevate to the level of bullying in schools.
Children in the lower grades of primary school can't accurately identify some incidents as bullying at first, but it doesn't matter, I just need the child to tell me the details of the incident, and I will make further judgments and take measures.
For example, when my brother was in the third grade, there was a boy in the class who liked to play tricks on him. The boy was bigger than him, and he liked to catch my child and play with him between classes and after school. It's a play, but it's not quite like it. Because he often moves very much, such as dragging my child's arm in a fast circle on the playground, and even pulling his schoolbag to prevent him from leaving, so that my brother's schoolbag strap is torn off (in fact, the schoolbag strap is quite firm, and it can be pulled and broken by him, so imagine how strong he is). 
The bag strap was torn and my brother was a good-natured child, or he was very self-aware and wouldn't fight with that child, but the child came home and complained to me. He also relayed a threatening remark from the child: "If you dare to talk to your parents, you will be even more teased." "Naturally, our brother didn't take his threat to heart, and when he got home, he told me all the truth of the matter.
My first reaction was that I had to contact the parents and tell them what their children were doing at school. Sure enough, the other parent didn't know. It's just that I didn't directly position this incident as school bullying. 
Add ** notes, no more than 140 words (optional) I initially positioned that children were naughty and liked to joke, and some children didn't even play lightly or lightly, because it really didn't cause physical harm to my children. I'm also giving the other party a step down. After two or three times of communication and exchange, this child is now basically distancing himself from my child. When it is necessary to get in touch, it is also a related issue of learning from each other.
No bullying is a sudden outbreak, don't expect children to define the scale of bullying, and don't expect the children you see to testify, the first step is to do a good job of effective parent-child communication, as the child's guardian, if parents can intervene as soon as possible, I think many signs of bullying may be strangled in the cradle.
