Recently, young doctors often consult about studying abroad, such as choosing a study destination. I think you need to do your homework carefully to find out the fields you are most interested in and where the best centers in the world are. You must not go abroad just for the sake of going abroad. Other related questions were made more clear in my last essay, "Why did I choose to study in France?" A lot of people then asked me with interest what I learned in France? Although it was nearly 20 years ago, it is still vivid in my mind. Many things were not taken seriously at that time, but they actually had a profound impact on me personally. So I wrote an essay for the readers.
