To continuously expand the scope of the study. The complexity and comprehensiveness of our work, decided to not only do we want to be professionals, or if generalists, to dabble in different areas of knowledge. Mastery of knowledge not only to have knowledge to rational analysis. This on requirements we, not only to learning national of route, and approach, and policy, also to learning national of legal, and regulations; not only to with political theory armed mind, also to with economic theory guide work; not only to read history, also to read history; not only to absorption SM of mirror, also to gets is of road; not only to from local learn, also to to outside learn; not only to to books learn, also to field study learn. 　　Therefore, I would encourage you, and more to the outside world when I have time to take a look at, take a stroll, outside developments, learn other peoples development approach, and then come back to gu
