I remember Zhong Nanshan, China's Dr Fauci equivalent saying, in Feb/Mar 2020 I think, that if the rest of the world followed China's policies covid would be eliminated by June (2020). I wish we'd actually done that.

Early covid was a bit easier to stop I think than omicron. Both China and Taiwan have had over 50 cases a day since mid Jan which illustrates it's hard with this one.
