General Chinese Thread

I was learning chinese for a year or something.
But I still have a lot of questions.

for instance what variant is correct

1) 我少会说中国
or
2) 我会少说中国

In the opening of the 2004 movie 功夫 Kung Fu Hustle, the wife of the leader of the Crocodile Gang addresses the leader of the Axe Gang as 「大哥」.  Does this mean she was his younger sister (which seems plausible given that she's married to a crime boss), or was that just a respectful term of address?
