1、? Hownet has nothing to say. Basically, everyone should know that as the core representative of authoritative literature sources, most universities in China have cooperated with HowNet. At present, China HowNet has developed into an international advanced online publishing platform integrating journals, doctoral dissertations, master's dissertations, conference papers, newspapers, reference books, yearbooks, patents, standards, Chinese studies and overseas documents. The website of the Center is updated with more than 50,000 documents every day.

You can download documents for free on campus, and you need to pay off campus. (In fact, if you don't have an account, a treasure is also sold with a HowNet account, which is very cheap. )
