Only 2/3 fail air quality standards? I would have guessed at least 80%.
Well according to te article, those are Chinese standards, not international ones. The international standards are almost twice as tough as the Chinese ones.

The Chinese(the Taiwanese too, although they are improving) alter their 'standards'. So even those cities they claim meet standards for air quality, would fail if international standards were applied.
In my experience, Taiwanese were actually worse than Chinese ones for air pollution. I was able to see a blue sky in most of the Chinese cities I've visited - I can't say the same about Kaoshiung or Hsinchu. Even Taipei was smoggy most days I was there.
It really sucks when you visit a place and all you see is grey haze everywhere...

In fairness, humidity exacerbates smog problems. In the bad old days in Los Angeles you could look at the humidity for the day and calculate air quality off of that.
The down side of low humidity days coupled with pollution is you get increased ozone levels.
Curiously, in the Sacramento region, every summer day when there's a warning on ozone levels the ozone maps always show the bloom starting at the Intel plant in Folsom. Maybe it's a coincidence, but it's extremely consistent.
