Recently, a short video posted on Twitter shows a crowd of Chinese medical workers in protective suits holding banners and protesting for better treatment on the street. They are usually called "Dabai" or literally "Big Whites" for their common appearance.

According to the video uploader, these "Big Whites" work at China Construction Second Engineering Bureau Hospital in Beijing.

In the video, a hazmat suit-clad worker is holding a loudspeaker, shouting, "Don't let the anti-epidemic heroes sweat and cry."

And then others echo, "Want to work and want to eat."
