Getting any kind of medal is done 由 contributing to the club. 你 need to add 图片 and videos, make polls, write 文章 etc. Contributions which get a lot of 粉丝 或者 评论 are best. It takes a while, so 你 also need to be patient. Honestly, it's better to just contribute because 你 want to and just let 奖章 come, rather than focus entirely on them. That way 你 can become annoyed.
