Abstract: An information sharing method and related terminal device are provided. In the method, a first terminal device first establishes a communication connection to a second terminal device. When the first terminal device approaches a third terminal device, the first terminal device performs identity authentication on the third terminal device through near field communication (NFC). After determining that the identity of the third terminal device is valid, the first terminal device sends communication link information to the third terminal device by using a short-range wireless communication technology. After receiving the communication link information, the third terminal device establishes a communication connection to the second terminal device by using the communication link information when detecting the second terminal device. In the foregoing solution, communication connections can be quickly and conveniently established, and information sharing can be implemented among a group of terminal devices.
