First of all, let me tell you a general direction. The topic can be changed at any time, provided that you discuss with your tutor, and the decision-making power and leading direction of your graduation thesis are your tutor. R Second, the scope of the topic is actually too large, and it is easy to get smaller. It can be defined by adding a subtitle, or directly-in the case of xxx, it can narrow the scope. R Third, the title and outline of the paper only provide a direction for yourself. The teacher should grasp the direction and depth below, and then make sure you don't write crooked. If it says it's better to write it another way, that's no problem at all. The premise is to communicate well with the tutor, and then feel that it is no problem to increase homework. Of course, tutors generally support and advocate students to have their own ideas and thoughts. r
