During rush hours, especially when there is a distinct possibility of physical contact between co-passengers, I would feel more comfortable with women instead of men around. I'd rather walk 10 miles than being pushed and stacked like a sardine in the subways cars or buses!
I’ve lived in China for quite a considerable time including my graduate school years, travelled and worked in a few cities and still choose my destination taking into consideration the density of smog or PM2.5 particulate matter in the region.
