Academic Hall said that the innovation of thesis topics is inseparable from the training of students' thinking, especially divergent thinking, that is, from the central point of thinking, through multi-angle speculation, from different aspects, using different methods to investigate and analyze topics, get rid of the shackles of thinking patterns, break the influence of conventional thinking paradigms, capture the goals of thinking, find innovative points, and develop the diversity of topics.

We can innovate the topic selection from the following aspects:

1. On the basis of inheriting predecessors' achievements, seeking common ground, seeking common ground while reserving differences, find out the shortcomings of others' research, then supplement and deepen this aspect, and find out the problems and their depths that others have not involved with a different perspective. Carry out your own innovation and expansion on the basis of learning from others.

2. Looking for topics in the gaps of academic research, looking for blank areas that others have not discovered and involved, instead of "platitudes", thinking what others think and being the first.

3. Reading literature-the way to get innovative inspiration or problem-solving methods

4. Use multi-directional, reverse and heterosexual thinking to select topics.

This is an unwelcome topic.
