I always believe that we can learn something from the helpful forum. So any comment is warmly appreciated! And in fact my profile may seem a little bit weird since I only spend 2 years in my home institution, then during my exchange period in Master 1 international program, which is my junior year, I was admitted into a formal master program (Master 2 ETE program in TSE)and will be granted a master degree in my senior year.

Many thanks for your kind patience in advance.
