Choosing a topic is to determine the professional direction and solve the main problems clearly. It is best to combine personal interests with the actual situation. Attention should be paid to these aspects: quick solution, advance, expected ideal effect, feasibility, moderate scope, finding blank spots and weak links, having sufficient information and giving full play to one's own specialties.

Academic: It is required to apply scientific principles and methods to scientifically analyze, rigorously demonstrate and abstract new problems. Academic papers should be argumentative, at least with opinions. It's not a work summary or a manual.

To be innovative, at least be innovative. Whether there is innovation is the most important starting point for many publications to consider employment! It can be said that there are two kinds of innovation: original innovation and integrated innovation.

The best is "four innovations" or "one innovation": new fields, new ideas, new materials and new perspectives. The content combines the knowledge learned and extracurricular materials.
