Abstract: A message order-preserving method includes that a first electronic device generates a first message to be sent to a second electronic device, and starts to send the first message to the second electronic device. The first electronic device generates a second message to be sent to the second electronic device, and before sending the second message to the second electronic device, determines that sending of the first message is not completed. The first electronic device sends an integration message including the second message to the second electronic device. After receiving the integration message, the second electronic device displays the first message and the second message based on the integration message.
