Doctors are a group with high academic qualifications. Do they spend all their time studying, or can they take part-time jobs in their spare time? If you do a part-time job, what kind of part-time job can make full use of your education and experience? Handing out leaflets is hardly done, because it is really a waste of time and the return is low. It is important that anyone with any education can do this kind of work, which does not reflect the academic advantages of masters and doctors. Recommend a part-time job that is more suitable for master's and doctoral students. The pro-test is ok, and it is a guide to academic paper writing. Generally speaking, for papers that have not passed the review, the comments are modified next to them. If it is published in general, an article of 4,000 to 6,000 words will take 200 to 300 yuan under the guidance. General publications are relatively simple and take less time, which can be regarded as a quick return and can be done in three days. Doctoral students generally have the requirement of publishing core journals. If they have published core publications, they can be teachers of core writing guidance. This income is very considerable, and the cost of guiding through a core is almost tens of thousands. Writing guidance is not ghostwriting, the author adjusts and modifies the article according to your revision opinions, and finally passes the review of the magazine. At the same time, you can also kill two birds with one stone by modifying other people's articles, gaining writing experience and understanding better journals.
