@vvalkyri @BoomSardonic @michaelmina_lab @YouAreLobbyLud @DailyJLee I'm not sure there is a single report of welded doors since early 2020. Perhaps it's completely suppressed but seems doubtful (wasn't successfully suppressed even then). It seems to be mostly travel restrictions and mass testing, as you say.
@vvalkyri@BoomSardonic@michaelmina_lab@YouAreLobbyLud@DailyJLee我不确定自2020年初以来是否有一份关于焊接门的报告。也许它被完全抑制了，但似乎很可疑（即使在那时也没有被成功抑制）。正如你所说，这似乎主要是旅行限制和大规模测试。
