First, it should be in the interest. In daily life, a person will not do things that he is not interested in, and he can't do well even if he reluctantly does. Writing a paper is the same as doing things. If you can meet your own interests, you may write well.

Second, we should consider our own abilities.

At present, the academic system of master's degree and doctor's degree in Taiwan Province Province is six years, but most master's degree is three or four years, and doctor's degree is four or five years, including taking credits. In fact, the time to write a thesis is only two or three years. During this period, we should also consider whether we have the ability to do research on a certain topic. If the topic involves too many foreign documents, you should consider whether you are competent or not.

Third, the scope should be moderate.

Generally, books on paper writing emphasize that the topic should not be too big or too small. The author thinks that the research direction should be flexible. For example, when doing research at the beginning, the direction should be bigger, and then narrow down the research direction after in-depth understanding. If we shrink the topic too small and look for information only by holding the topic all day, the pattern of researchers will be too narrow and it will be difficult to cultivate scholars' macro-generalization ability. Therefore, the Gocheck paper detection system believes that the length of research time and the amount of data should be the primary factors in the choice of research direction.
