As a quick point of reference - while historically I'm aware that Mandarin and Cantonese are two separate languages, and their are numerous other dialects, I'm going to assume from a mechanical standpoint that those who've invested skill points in Chinese/Mandarin or speak it as a native language are capable of speaking and understanding both.  I'm also comfortable with almost everyone who's been in Gomorra for more than a few months being able to offer salutations, ask very simple questions or very simple statements in languages that they haven't invested points into, at least in Spanish and 'Chinese' as there's a considerable population of both.  What I'll constitute as a reflection of their capacity for 'simple' exchanges will be a direct reflection of the character's Knowledge trait.<br/><br/>I'm mentioning this mostly because I know some people bought Cantonese/Mandarin on their character sheets, so now those players should be aware they're familiar with both languages.
