Waving, not drowning

The air quality is back down to normal levels, which doesn't account for the continuing smell of burning biscuits every time I leave the MTR in Causeway Bay.  Maybe it's a fragrance like freshly baked bread, that encourages people to purchase more frequently.  Or move out of the way to let taxis past.  Who knows how the psychological engineering of Hong Kong is conducted, what its hopes and dreams are, what laudable goals they aim to reach?
