Sarah, May I most respectfully suggest that your sentence needs revision. There are at least three bits of information that we need: 1. Is "Collectors" the name of a magazine? 2, What does "which was awarded by the magazine" refer to? (What was awarded?) 3. It would make for a better sentence if you told us the name of the artist. If you give us this information, then someone can help you write a clearer sentence.

His calligraphy was selected in The World Fine Arts Portfolio and he hold ninth rank among the Chinese modern calligraphers, which was awarded by the magazine —— Collectors in 2003.
