I don’t know about that, but I did find that some people in China are using zk. There’s no linguistic obstacle (I have both Chinese and English cards), and the categorical flexibility of zk lends itself to multicultural thinking.

A book that takes on what might be called the “Chinese structure of knowledge” is one to which I made a small contribution: Jack Chen, Anatoly Detwyler et al., eds, Literary Information in China: A History.
