Re: [NTG-context] pinyin in context

\documentclass{article}

You're not using ConTeXt at all. This is LaTeX code. Which is fine, but then this list is really not the place to ask your question :-) There are hyphenation patterns for pinyin that could be added to ConTeXt; it wouldn't be too much work, but you would need to specify how you would like ConTeXt to behave exactly. For that matter, the LaTeX syntax for pinyin (\ni2\hao3!) is not supported at the moment. Arthur
