I think that some portion of the Chinese figures for lost cell phone lines is the dead, but I'm guessing that number is going to be in the 6 figures, not 7 or 8. Whatever Italy has for a CFR, multiplied by their population difference. I personally peg China's death number from Covid to be around 200,000 +/- 20%.
Despite all their censorship, we're too connected and rumors and testimony through personal phone calls to family etc. would be leaking out.
