Hi,
we also moved here from Brussels, so if you need more info/comparison just let me know.
Pollution definitely is an issue and the last couple of weeks have been bad. I had to smile when I saw in Brussels last week that they had the ‘smog 90’ signs on the highway, when the air felt terribly clean compared to what we are used to in Shanghai….
Inside you can manage with air filters etc. but outside sports has to be adjusted to the pollution. A bit like checking the weather forecast before planning outside activity….
