A scheme of quantum direct communication using non-symmetric quantum channel superdense coding is proposed.In this scheme,the server prepares the initial states in two nonorthogonal basis sets which forbids any one to copy them perfectly,so the scheme is more secure.This scheme also has a higher capacity than other schemes,for using the ideas in non-symmetric quantum channel superdense coding.
