For Chinese, I went to Taiwan and took a beginner class, and I'm also going to mainland China soon where I'll continue to improve my Chinese. I've also been doing some self study, and sometimes going to language practice events or practicing with language partners.

For Japanese, I studied abroad in Tokyo during a summer, but I went a long time without practicing, and I'm trying to study again on my own now.

For the other languages, I watch videos on YouTube, I practice saying things out loud, and sometimes I try to write simple stories (with the help of Google translator, but I type everything up myself so I can learn from Google translator, even if it's not perfect), and sometimes I practice basic things with language partners.
