Fundamentally speaking, preschool teachers all graduated from preschool education. For example, I personally graduated from preschool education, and now I am a preschool teacher. The counterpart of preschool education is preschool teachers. In addition, some preschool graduates will choose jobs related to children's publishing and children's playing with teaching AIDS.

Preschool education is the name of a discipline and major, just like business administration and human resources.

As for the preschool teacher you mentioned, I don't know what you mean. One is to teach teachers majoring in preschool education, that is, we are university professors majoring in preschool education. One kind is the teachers who take the direction of preschool education, usually called early education teachers, early education trainers, baby nurses and so on. All fall into this category. Usually, teachers in this preschool education direction teach before the age of 6 or 7, and most of them will not work full-time. Of course, there are also wives who specialize in home-based parenting, which is another matter. I wonder if I can answer your confusion.
