I am going to meet my chinese girlfriend's mother for first time. What would be appropriate cha li

Cha li? What did you refer to? I guess that you want to bring her a present, right? If so, foreign brand cosmetics is a good option. And I don't think it's an appropriate chance for you to give Cai Li (Bride Price) since it's just your first visit. Just kidding! Don't be too nervous when you meet her. You know, many Chinese young boys are very nervous when they meet their girlfriends' parents. Good luck!
