Two provisos though.
1.Make sure they've been posted about at least once. You can use the search on the profile to confirm this.
2.When requesting, post them like they're currently arranged.* I.e. actor: nicholas tse, actress: tang wei, singer: eason chan, group: da mouth, etc. This is so that I don't have to go Googling for everyone and figuring out who they are and what they do.
*If they are singer/actor types, use whichever tag they are MORE known for.
