Would be great if you took a few minutes to improve the article then. Reducing the cultural bias of Wikipedia happens the same way as improving Wikipedia in general, one article at a time.
Thanks, I did contribute to Wikipedia long ago (the article about Confucius still has some sequels of my edits), but it happens that I have not enough knowledge on this topic. To me, reminding about Wikipedia's cultural biais is necessary, because many people think it is reliable and complete.
