Wechat talks about how to synchronize to Weibo.

This needs to be set directly on WeChat, which can be seen from the following:

First, open Tencent Weibo, move the mouse to the nickname of Tencent Weibo, and click the "Settings" button in the drop-down list that appears.

Second, find the "Synchronization Settings" category button on the left and click it; On the right, you can see a "WeChat WeChat official account Show". Click it to set it.
