Wow, this video is haunting and with no end in sight it makes you wonder what will happen to these people. I agree with @builderofcastles what good is the quarantine of millions if the virus is already spreading across the globe. I do not know what the alternative is, though.
I don't think they want scenes like this one getting out to the public and on YouTube if you enter the English title - this video does not show up. Instead we find videos of residents shouting "Jiayou' encouragement but the video you posted has 10x the views.
