A master's degree is sure to write a thesis. Theses in the master's stage are all related to the research topics in the graduate stage, which will be related to the research direction of the tutor. Therefore, the teacher is likely to give you a direction, but in the end, it is up to you to look up the information and write the paper in combination with the actual scientific research results. Master's degree is basically required for publishing papers now, and the level of published journals is also required.
