In fact, it is not as difficult as you think, as long as you calm down and follow the following steps.

1, in the hazy period, choose the general research direction and read the relevant literature in this field. To determine the research direction, we can search the references of relevant journals through China HowNet, EI, SCI and other databases, and get to know the mainstream research contents, research methods and research results in this field, so as to have a general understanding. At this stage, if you don't know much about the theory, you don't need to delve into it. We only know the purpose of the theory from a macro perspective, and the specific implementation can be decided later.

2. In the gestation period, understand the core theory and break through the theoretical application. If it is like engineering, you will know which theories are basic after reading the literature. If the theory is not clear in the hazy period, we can conduct in-depth research through relevant literature at this stage, so that we can apply the theory to the field we want to study.

3. In the growth period, imitate high-quality papers and deeply analyze the research ideas of the papers. At this stage, we should be able to reproduce high-quality papers in this field through theoretical accumulation in the gestation period. At this stage, it is suggested to reread the papers in the hazy period and screen out the papers with high quality and reproducibility. 4, mature, independent writing. After imitation in the growing period, we can intensively read the recent high-level papers in the mature period, grasp the starting point of their papers, and then start from the similar starting point, and quickly generate papers through the replacement of similar theories, data and application scenarios. In fact, many lab tutors can't guide students, and neither can our lab, but even so, the students with the worst theory in our lab finally graduated as scheduled through the conference paper. This article is not as difficult as you think. As long as you write it, it will be published regularly.
