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

When conference in an workplace, individuals will put on masks. At foods, diners will sit following to each other or in a zigzag pattern, not instantly throughout. Hotel rooms will be ventilated for fifteen minutes just after travelers check out. Visitors at zoos and aquariums must stand 6 toes apart. Shouting and hugging will be discouraged at sporting functions. So will large-fives.
