Li Bai, for one (4)
I believe the answer is:
poet
'li bai for one' is the definition.
(I know that Li Bai has the occupation poet)
This is the entire clue.
(Other definitions for poet that I've seen before include "Heaney or Yeats, say" , "Rhymer" , "One writing verse" , "author" , "Eg, Keats or Auden" .)
