hi Oyamakuma,

When I started learning Chinese, I would divide my time into blocks devoted to different activities (reading textbooks, watching Chinese cartoons, listening to podcasts, etc.). This was valuable at the time, because my Chinese was poor and I needed structure.

I don't study that way anymore. Now I live in China and am immersed in Chinese for most of the day. Whether at work, at home, at a restaurant, playing music shows--there's Chinese everywhere. Of course, having Chinese friends, a Chinese wife (and inlaws!) and a job at a Chinese university help a lot.

Here are some other ways I use Chinese throughout the day:

-listening to podcasts at Popup Chinese :-D

-Chinese social media, like 微信, 微博 and QQ

-my computers, cellphone, and most of the applications I use (Microsoft Office, Google Chrome, etc.) are all set to Chinese localization

-correcting my students' homework

-Lang-8 for practice with written Chinese

-flashcards (Anki) periodically throughout the day

-in my spare time I

* play video games (currently 《去月球》)

* read books (currently 《流行音乐与爵士乐和声学》), or

* read articles online (usually from 百度百科 or 维基百科)

For sentences or words I don't know, I use Wenlin on my computer or Pleco (with paid add-ons) on my cell phone. Then I make Anki flashcards for stuff I want to review later.

When I'm confused about a grammar point I usually ask Grace in the forums here :-) There's also John Pasden's fantastic Grammar Wiki:

I'm not sure how much time I spend on Chinese a day! Probably a lot, but I care about frequency more than quantity.
