South Koreans angry at North Korea's perceived "hijacking" of the Pyeongchang Winter Olympics have sarcastically dubbed it the "Pyongyang Games", but it seems many really are struggling to differentiate between the two places. Hundreds of Twitter users in recent days have referred to "Pyongyang2018", and while some were making a dig at the presence of North Korea at the Games, in many cases it appears to have been a simple mix-up. The two are easily confused, but there is a world of difference between them: Pyongyang is the capital of nuclear-armed North Korea, while Pyeongchang is the South Korean region hosting the Winter Olympics.
