Imperfect workaround: Right click the new sandbox running Tencent Meeting and enter Sandbox Settings. Go to Resource Access > Window Access. Click Add to add a new item providing an asterisk (*) as its name. Apply this modification. Open Tencent Meeting to test screen sharing. In addition, if any bluetooth device is used, append “OpenBluetooth=y” under the section of [tencentmeeting], the name of the sandbox holding Tencent Meeting, in the configuration file which can be edited via Configure > Edit Configuration. Without this enabled in my computer, screen sharing of Tencent Meeting also fails. In my testing, it can work at most times with those modifications but still occasionally fails.
I also have a site on wordpress.com. You know, wordpress.com is blocked in China, so I just used that site as a backup. It works perfectly in my last devastation of data loss. I recovered my lost posts from this backup site.
However, there is a problem. When I post a blog, I have to do it twice. One on nanzt.info and the other on nanzt.wordpress.com. I have to feel lucky I have only two mirror sites. Therefore, I decided to test this plugin, namely Push syndication. The latest version v2.1 is only availale on github.com. (There is a 2.1-wp branch, grab it as a zip file, and upload to your own-hosted website.)
Be aware, this version from the github only works with php 7.1. The reason is the scripts contain a function named mcrypt_*, which has been deprecated in php 7.2+.
