About 25 million residents in Shanghai have been shut in their homes since early April, as officials rush to curb its worst ever outbreak since the beginning of the pandemic.
Shot against a simple aerial black-and-white view of the city, the video opens with audio clips from media briefings in March where officials say Shanghai will not have a citywide lockdown. "We have gone to the hospital twice, but no one is there to treat us," a man whose father is ill is heard saying.
Internet censors battled for hours Saturday to scrub the video from Weibo and Wechat, as netizens kept uploading it into different cloud services.
