In case you were wondering, (I know I was!) there are ample los bathrooms in Shanghai including "1,089 fixed toilets and 25 movable toilets, owned by a government department called Shanghai City Appearance and Environmental Sanitation Administrative Bureau. Apart from the bureau's toilets, private-enterprise owner Gu Hongchang built 140 movable toilets. "In total, the city has over 1,200 toilets, which means, on average, there are three toilets per square kilometre..."

How do you spell relief? DECENT TOILET!
