It has been three weeks since the start of the school year, but the school and classroom services are still not yet ready. Not only are the children adapting, but also the teachers need to adjust to the children they will be leading in the new school year, and it takes a lot of effort to teach and establish good communication with the children's parents. Not only are children becoming more difficult to teach, but parents also have many demands, so it's no wonder that the shortage of teachers at all levels of schools and kindergartens is getting bigger and bigger. When the school year started in August, there were many children who were absent from school and every class was absent.
