As far as I know, no. I think the only formal translation that has been done is the French one. There was another amateur one for a smaller niche language I gave approval to. When we first released HoW we had an inquiry about it from a Chinese Publisher, but I never heard back.
Alas! Networking can be a frustrating thing!
I do suspect that a full Hearts of Wulin Chinese translation would have to make major changes to the text: large parts of the core-book, after all, are devoted to explaining aspects of the Wuxia genre that folks raised in Chinese culture would likely be more familiar with.
