Man candy is a man who is superficially attractive to look at or a man who has an attractive appearance but who may be vapid and lack substance.
Man candy(草包美男)指外表很吸引人的男子;或者徒有迷人外表，但其实很无趣又没有内涵的男子。
For example:
Ken is a sweet piece of man candy, Debbie has to be told that looks are not everything.
肯就是个甜美的草包美男，我们应该提醒德比，告诉她外表并不能代表一切。
