Based on the order rearrangement of single photon sequence, we present a multiparty controlled quantum secure direct communication protocol. The present protocol can be applied to some special scenario. In the protocol, the sender's secret message can only be recovered by the receiver under the permission of all the controllers. The security for the protocol is ensured by the quantum no-cloning theorem and the secret transmitting order of the single photon sequence. Moreover, all photons are used to encode the secret message except those chosen for eavesdropping check and it is unnecessary for the protocol to use entanglement. Our protocol is efficient and practicable.
