What do you think of kindergarten girls peeing behind trees in the street after school?

The self-control of kindergarten children is still very poor, which has reached the point where they can't help it. How can you let the child hold it? It's still uncivilized, but you can't help it, but adults still have to tell their children that it's okay to go to the toilet after school and it's unsightly in public places, but I don't want this to happen again. As long as adults make it clear to children, I believe children can still understand.
