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.
Quando os níveis de PM2.5 extrapolaram os gráficos em 2012, descritos como "loucamente ruim" num tuíte da embaixada norte-americana, os chineses foram para as redes sociais e começaram a questionar por que havia essa desconexão entre as estatísticas oficiais de qualidade do ar e o que eles próprios viam e respiravam.
