On air quality...

Beijing, 23:00 hours, last evening

Sis is in China this week spending a few days in the grasslands of Inner Mongolia/Beijing.  *Cue patriotic music*  So patriotic she is... promoting Singapore during National Day week! *Cough! Y-e-ah cough R-I-G-H-T cough!*

Last night before she slept, I asked her how's the pollution situation in Beijing, any smell, need to wear mask or not?  She replied, no burning smell, but you can't see the sun, like Shanghai.  (How is that statement not alarming by itself?)

So I sent her the above screenshot and said "RED BARS LEH!" And still she insisted can't see lah... (OMG! Do you have microscopic eyes? special x-woman powers? How does one see PM2.5 particles?)  

Singapore, 22:00 hours, last evening

This is the situation in Singapore.  No red bars (YET!) but forests are starting to burn in my favourite neighbour country.  Perhaps it's time to stockpile the 3M masks and replace the air filters...
