On September 20, 2019, Dr. Cui jingbo from duke university in kunshan came to the school of low carbon economy upon invitation. First of all, the teachers who applied for the project from the ministry of education reported their project application forms, and Dr. Cui jingbo guided the project application forms. After that, I analyzed the topic selection, topic determination, structure, logic, technical route, key issues, difficult points, key references and other details of the subject to be applied for by our college in 2019, and interpreted the project items applied for by our college and social science fund one by one based on my own experience in applying for the subject.
