i'm not really fluent so i just lurk and translate anything i don't know. most of the time i'll just browse zhihu or baidu and find new terms. sometimes i'll find stuff that i wouldn't on english sites. it's also become my go to "immersion" study method.
Chinese websites particularly baidu and weibo don't open for me. Not sure if it's because of my ISP or whether these websites are restricting traffic. Not that I would be able to understand anything on them.
