Hey, I'm a Korean girl who grew up in the East Coast and pretty much fluent in both languages. I took mandarin for several years in high school and also spent a considerable amount of time in Beijing/Harbin. But I haven't used it in a while (say, a few years?) and I really want to start getting it back. I would love to meet a friend who can meet with me once a week over a meal or coffee and hang out (and also let me practice Chinese). I can definitely help you with Korean or English if you wished.
