SEOUL—After two months of intense social distancing, South Korea is about to open up. And it has a rule for every thing.

When conference in an office environment, men and women will put on masks. At meals, diners will sit upcoming to every single other or in a zigzag pattern, not straight throughout. Resort rooms will be ventilated for fifteen minutes after vacationers check out. Site visitors at zoos and aquariums must stand six ft apart. Shouting and hugging will be discouraged at sporting activities. So will superior-fives.
