China's economic capital, populated by 25 million people, is facing its worst outbreak of Covid-19 since the start of the pandemic.

The Ministry of Health announced on Saturday 12 new deaths and more than 23,000 new positive cases in Shanghai.

This is a rebound of nearly 6,000 cases from the previous day.

Local authorities attribute this new increase in particular to overcrowding in certain old residential buildings, where kitchens and toilets are shared.

Almost all Shanghainese have been confined to their homes since early April.

Many residents have difficulty getting supplies of fresh produce and seeing a doctor.

Titled "Siyue zhi sheng" ("Voices of April"), the six-minute video is a long sequence shot of Shanghai filmed from the air.

The author has added to these black and white images, in chronological order, a succession of sounds taken from press conferences, videos published on social networks or telephone calls from residents.

The video begins with the voices of politicians declaring, at the start of the outbreak in March, that a short preventive lockdown is undesirable, due to its economic repercussions.

This initial hesitation led to the explosion in the number of positive cases, which finally triggered the current confinement which is expected to last for many weeks.

The video presents the repercussions with about twenty sound clips: confined inhabitants who are unable to obtain food, medicine or go to the hospital;

a man prevented from returning to his confined neighborhood;

or a woman describing the chaos in quarantine centres.

The video was massively shared Friday evening on the WeChat social network.

But the censors managed to erase all traces of it in a few hours.

"The author is just presenting raw facts. There is nothing provocative!", Annoyed a user of the Weibo social network on Saturday, where discussions on the subject are almost completely censored.

"This video is nothing special. Its content was already known. But the fact of seeing that even that is censored, it bothers me. That's why I reposted it on my feed", wrote another user.

As a sign of discontent, many netizens shared on WeChat music videos of two songs with protesting lyrics: "Do You Hear the People Sing?"

(from the musical "Les Miserables") and "Another Brick In The Wall" (from the band Pink Floyd).

The first is a call to rebellion.

The second criticizes in particular "thought control".
