Thesis, which means talking and exchanging ideas in classical literature, now refers to articles that conduct research in various academic fields and describe academic research results. A paper generally consists of title, author, abstract, key words, text, references and appendix. It is not only a means to discuss problems in academic research, but also a tool to describe academic research results in academic exchanges.

Undergraduate course refers to the basic component of higher education, which is generally carried out by universities or colleges, and few higher vocational colleges carry out applied undergraduate education.
