The library network can be connected, the Internet can be accessed normally, and HowNet can be accessed.

HowNet downloads documents. It is recommended not to click Download directly in the search results list. The papers downloaded from these places are all in CAJ format unique to HowNet, rather than our common PDF format documents. A good habit of downloading a paper is to click on the title of the paper, enter the paper information browsing interface, and then select "PDF Download" in this interface. It should be noted that HowNet's dissertations are only downloaded in CAJ format. At this point, you can only open CAJ browsers after downloading and installing them.
