> nobody really knows why they've been successful It's not much of a mystery. The lockdown was much more complete, and was accompanied by additional measures to separate and quarantine sick people. There message wasn't, "Stay home if you're sick (and infect your families, and maybe your neighbors too)." Sick people quarantined apart from their families. People went door to door to measure temperatures. Food was delivered to neighborhoods, so that people didn't have to go out at all. That's how they brought the number of active cases to a low, manageable number. Now, they have extensive testing, and they use cell phone data to assist contact tracing. Basically, what's needed is a capacity for organization and discipline that seems lacking in many countries that are struggling.
