I’ve been talking with friends about what happened during zero Covid. Friends outside China say, “You have to let us know what really happened.” Friends inside China share personal stories and rumors. However, it seems pretty obvious that no one knows what happened. We know what we saw on our WeChat feeds. We know what family and friends have told us. We know what we saw and overheard while waiting in line for our daily test. But. That seems to be all we know.
