Possible plot-hole question
Okay. In the beginning of the movie, Jing Mei is playing mah-jongg with all her aunts. Ying-Ying goes "aiyaa!" and starts the others talking in Chinese. Then Jing-Mei goes "hey, no talking chinese! How do I know you're not cheating?" or something. Wouldn't that indicate that she doesn't know Chinese? And in the end she's like...talking to her sisters in perfect Mandarin...
I don't know. Did I miss something?
