i want someone who can speak korean with me

Hello Yenan,

You better look for native Korean speakers on the left side of your homepage in the 'language partners' section ,ones who eventually would like to learn Chinese as well.
Contact them through emails and friend requests for potential exchange.
You will get a better chance to get in contact with many members as possible, better than just posting it here in the questions and answers section.
Wish you luck :)
