To write a thesis, we must first start with the topic. According to your example, when you are looking for the stronghold of your thesis, you can inquire about the information or ask the tutor, and then make your argument according to the information you have inquired. You can borrow the relevant literature from the library to make an investigation, or you can elaborate your thesis arguments according to the thesis arguments of your former seniors and sisters. In short, you should write your own concept paper in your own language.
