They already had masks on when others questioned their effectiveness and to this day, 95% people wear masks outside.
They have hand sanitizers on pretty much every shop entrance and chairs are placed with certain distances apart.
They don't wear shoes at home and public spaces don't have litters all over.
They don't hug and kiss frequently like some countries do.
Some stop visiting restaurants when they read news that daily infection count goes over 100. (Not 10,000.)
Apparently they don't riot shouting in the middle of the outbreak.
How about that they have been acting clean before covid happened and government not exactly handling the situation strictly wasn't really the cause of the difference in death rates?
Also interesting is that they have a train system with packs of people squashed in a cabin but the infection rate is still low and someone needs to prove/disprove the BCG vaccine theory.
