Can the financial report not be included in the appendix of the paper?
Of course. The financial report can not be written into the appendix of the paper, mainly for some contents that are not suitable for the text but have reference value, which can be compiled into the appendix. For example, samples, questionnaires, charts, examples, lengthy formula derivation, algorithms, language programs, explanation and demonstration processes, etc. If you don't have the above content in your paper, you can ignore the appendix.
