Enlightened by Zhang and Cheung's original idea [J. Phys. B 41, 015503 (2008)], we put forward a novel tripartite quantum information splitting scheme by using three Einstein-Podolsky-Rosen pairs as quantum channels. Our scheme is applicable for perfectly splitting four ensembles of quantum information known by the splitter in priori. In contrast to the general scheme using the same quantum channels [Eur. Phys. J. D 39, 459 (2006)], our scheme has distinct advantages in quantum resource consumption, quantum operation intensity, classical communication cost and efficiency when dealing with the four specific ensembles of quantum information.
