english: When PM2.5 levels went off the charts in 2012, or "crazy bad," as the US Embassy once described it in a tweet, Chinese denizens took to social media and they started to question why it was that they were seeing this disconnect between official air quality statistics and what they were seeing and breathing for themselves.
non_english: Keď hodnoty PM2,5 v roku 2012 vystrelili nad grafy, alebo „šialene vysoko“, ako to nazvalo americké veľvyslanectvo, tak to medzi obyvateľmi rozvírilo diskusiu a pýtali sa, ako je možné, že vidia nesúlad medzi oficiálnymi údajmi od úradov a tým, čo vidia a sami dýchajú.
