this câu hỏi has been asked like a bajillion times, but i'll still answer it anyways, bạn can get huy chương bởi contributing to the club u want to earn a medal in. bạn have to đăng tải pics, videos, write alot on the club's wall, get involved with the forums, make pop câu hỏi kiểm tra questions, answer peoples questions...then at a ngẫu nhiên time bạn get a medalXD hope that helps!
