If you want to publish a thesis topic, you have to find a major. Now some people are searching online, and there are many official website, some of which are just a cover, and some are posted on Taobao, which makes people more dangerous. I suggest that you look for predecessors who have published papers, and ask them to recommend publishing institutions for you, such as Hengzhe Medical Journal Network, focusing on periodical publishing, or you can find good periodicals yourself and check them on HowNet or Guoxin.
