Don winland is our china business and finance editor. He moved to shanghai at the beginning of march, and has ended up in the largest city wide locked down in history. From his window, i have a view of a free way. When i go downstairs for my covet, it's very ghostly. There's nobody on the streets. Often you'll see long lines of people dressed in the white hasmat suits. The health workers cind of strolling along in single file lines. It does look really strange.
