In fact, people who have been abroad before have the same feeling, and English has made rapid progress. However, some people say that after studying abroad for a year or two, they finally learned nothing and didn't even improve their English. That is, these two years, I played a huge game outside. If you go out to study for graduate students in foreign universities, you might as well go to some better universities in China.
But if you are a teacher who is going to resign and go abroad for postgraduate study, don't forget what you are going abroad for. If you really want to improve your ability, that's another matter. But if you want to give yourself a promotion and salary increase through this graduate diploma, it's actually a little different. Because the expenses abroad are actually very large, and the national policies may change in the past two years when you have no job, it may not be conducive to your employment when you come back from studying abroad.
When I come back from studying abroad, in fact, many people are already in the third year of high school, and it is time to get married. If you study hard abroad for two years and get married soon after you come back, it actually has a great influence on the stability of your job.
So in my opinion, there is no need for teachers to resign and go abroad for postgraduate study. Because this investment not only has a low return rate, but also you have to get married when you come back from studying abroad, and your job is not stable at all.
