(I have broad interests in many aspects and grasp the essential knowledge of the major, but I think at present, I can do many things in a superficial level, but not be competent to do things professionally owing to lack of ample knowledge and ability. So I think further study is still urgent for me to realize self-value. On the other hand, I think I can do a deeper research in my favorite area and communicate with high level teachers and students through the postgraduate study. And all these can improve my professional literacy.)
