Wechat says there is no space mark.

This mainly depends on what you publish.

Whether you send a video or a picture to a circle of friends, as long as it is forwarded from qq space, it is marked with an icon. If pictures and videos come from other places, there will be no icons when you send them to your circle of friends.
