When I read the research of professors, I was very happy but after talking directly with the professor I am very depressed, I feel bad for not speaking English well. Since I quit studying English since 2002 so when communicating with professors are very limited. Everyday, I berate myself for the limited knowledge. I'm sorry to bother you Pham Thanh Nam when he introduced me to a professor that I would do no good.
