1, there is no problem in the cross-major exam, especially if it meets your interest.

When you say two years, do you want to study for a master's degree? Specialization is practice-oriented, in fact, it is to train teachers in a specific field of practice. Theoretically, I am a kindergarten teacher after graduation. Of course, kindergarten teachers are popular in recent years, and the employment of master graduates is definitely no problem, but the treatment of kindergarten teachers is generally low among teachers, so you should be mentally prepared.

3. If you want to do other related work, it is the teaching and research work in preschool education. It's best to get an academic master's degree, which has developed rapidly before going to school in the past two years. Many schools have offered undergraduate courses in this major. At least now, it is possible to find a university to do teaching and research after graduating from a better school, but it is hard to say before you are admitted to graduate school. Other related work is not particularly related to this major-such as college counselors, civil servants and so on.
