In this paper, we propose an asymmetric controlled bidirectional transmission protocol. In the protocol, by using the thirteen-qubit entangled state as the quantum channel, Alice can realize the transmission of a two-qubit equatorial state for Bob and Bob can transmit a four-qubit equatorial state for Alice under the control of Charlie. Firstly, we give the construction of the quantum channel, which can be done by performing several H and CNOT operations. Secondly, through implementing the appropriate measurements and the corresponding recovery operations, the desired states can be transmitted simultaneously, securely and deterministically. Finally, we analyze the performance of the protocol, including the efficiency, the necessary operations and the classical communication costs. And then, we describe some comparisons with other protocols. Since our protocol does not require auxiliary particles and additional operations, the classic communication costs less while achieving the multi-particle bidirectional transmission, so the overall performance of the protocol is better.
