Good day !
I can understand that Mr. Century has had a trouble on his visa from the attached file.
However, because of many mistakes in the English grammar, I could not understand what Mr. Century wanted to me from the attached file.
Moreover, if he doesn’t study the correct grammar on English, he cannot publish sufficient papers in the international journals and proceedings.
So, I want that Dr. Nunthawath instructs Mr. Century on the correct English sentences.
