What are the nurses and class teachers recruited in kindergartens?

Nurses are usually called "aunts". In the class, I am mainly responsible for hygiene, children's lunch and snacks, watching children take a nap, and usually helping teachers look after children. Generally, there will be two teachers in the class, one is the head teacher and the other is the counterpart teacher. Supporting teachers should also attend classes and educate children. Their responsibilities are similar to those of class teachers, but the responsibilities of class teachers are a little bigger, and they are generally experienced teachers.
