1. The employment rate of preschool education is quite high, but the salary is generally not high. The key is what kind of kindergarten you teach in. Some kindergartens are better paid and some are worse. Enter a kindergarten with good welfare and look at your own level.
2, learn a little basic children's dance, music, piano playing, art, these are very simple. You should be able to master it after college or college courses.
If you plan to be a kindergarten teacher, you'd better like children very much, be patient and careful.
