@VGrubsky @MichaelSFuhrer It depends what you mean by fail. There are small single digit community cases still being found (down from 10ks). The hope in both Shanghai and other cities is that regular mass testing can substitute for long painful lockdowns, but that's not exactly proven so far.
@VGrubsky@MichaelSFuhrer这取决于你所说的失败是什么意思。仍在发现小的单位数社区病例（低于10公里）。上海和其他城市的希望是，定期的大规模检测可以取代长期痛苦的封锁，但目前还没有确切的证明。
