The reason of the 19th National Congress cannot be changed by everyone. /kloc-maintenance started on the night of 0/7, and cannot be modified during the period of 3 1 night 12:00, such as QQ, personal wechat or official wechat account name, personalized signature (introduction to the functions of official wechat account), avatar, etc. I suggest you revise it in June 1 1.

Extended reading:

QQ signature and space talk about the method of synchronous setting;

1. Log in to QQ and enter the QQ client interface. Click on the pinion (System Settings) in the lower left corner of QQ interface to enter the system settings interface.

2. In the system setting interface, click the permission setting icon to enter the permission setting interface.

3. In the permission setting interface, we can see that there is an option in the center of the interface called updating QQ signature synchronously during the call.
