@fergal_whatever @FinchTH Some of the "zero covid" countries probably relied too much on border quarantines with a "soft center" (including China in 2020, less so now) and would have had to improve internal measures to stay green without constant disruptive lockdowns.
@fergal_whatever @FinchTH 一些“零疫情”国家可能过于依赖具有“软中心”的边境隔离区（包括 2020 年的中国，现在不那么如此），并且不得不改进内部措施以保持绿色，而不会出现持续的破坏性封锁.
