I believe this might be a fonts issue? It sounds to me like the correct unicode sequences are being used (in any case ConTeXt should be able to handle that without problems), but perhaps the output font does not have a way to show the characters?

Are you able to test with another font which definitely does have the right glyphs to render Chinese characters?

[zhangzq71]

My system can render the Chinese characters with many fonts, where is the statement to specify the font?

[mszep]

It will be in the template.tex file, and you may have to enable certain fonts in ConTeXt. Unfortunately I can't help you with that as I've never done it before.

I'm also face the same situation. After some google. I think should use \definefontfamily in style files.
