At the morning meeting, one of the ones that flew in from the office was very petite, and kept hitting the glass, probably trying to fly out.
The morning meeting is over, little one

Still hitting the glass, as the saying goes, don't hit the south wall and don't turn back, it's all bumped and still hasn't looked back, it's more persistent.
The colleague carefully helped open a window, the little guy ignored it, still stubbornly bumping into the glass, getting a little closer, and flew away from the window in panic.
Until the cleaning sister reached out and grabbed it, so casually reached out...
Then after everyone watched, they sent it out of the window, and the little guy flapped his wings and flew away.
At first, I thought it was a sparrow, but later I found out that it was not, and it was like this on wikipedia
