Night Trains from Shanghai - Xiamen

I plan to travel from Shanghai (any station, Hongqiao or the main station will be find) to Xiamen. So far, I only find the fast trains (G,D) running during daytime. Because I don't want to waste the whole day on the train, is there any night train which doesn't take so much time to travel - about 8-10 hrs. Please advise me too, thank you!
