According to the habit of asking questions in regular undergraduate graduation thesis defense, it will be put forward around the procedure of the thesis itself, with little difference, which will infinitely increase the depth of the problem, so the main problems that may arise are as follows:

1. What are the local government debts?

2. What are the risks of local government debt in China in recent years?

3. What are the causes of local government debt?

4. How to resolve local government debt (how to resolve local debt risks)?

Other suggestions: be familiar with and remember the details of the paper as much as possible, such as the time when similar authoritative academic opinions were put forward, the author's country, name and source articles and comments; Prepare at least one detailed case that is not quoted in the paper, and avoid asking questions from different directions and explicitly asking for answers with materials outside the paper.

I hope it will be helpful and adopted.
