Extended information

WeChat group is a platform for multi-person chat and communication launched by Tencent, which can quickly send voice messages, videos, pictures and texts through the network. Users can communicate with their friends through WeChat in a richer form, similar to SMS and MMS.

The WeChat group is equivalent to a discussion group, and there is no group number displayed. After the WeChat group is created, all members in the group have the right to add others to the group when the number of people in the group has not reached the upper limit. Please select the function key in the upper right corner of the WeChat group -> Press the "+"sign -> Choose friends to join, or you can scan the QR code of the shared group for those who need to join the group to enter.

note: to join the group, you must be invited or scan the QR code in the group to enter, and active joining is not supported.
