I'm currently in Shanghai. I can confirm that parts of the city began lockdowns in early march, and on april 1st th city implemented a city wide shutdown. Most stores, including grocery and convenience stores, factories and plants, and schools are shut down. There are camps of people being quarantined at various centers in the city. Everybody has been tested multiple times, upwards of 15-20 times depending where they live. People are struggling here.

I agree that you shouldn't trust a lot of what comes out of here, but it is happening in Shanghai. The reasons are tbd, but i do believe they are trying to start the covid narrative again.
