Dear Log,
«In a battle of wills, the [Seoul] city authorities pulled down subway advertisements by the central government which claimed that Seoul had the worst standard of living among the world's 20 biggest cities. Another discarded poster featured a cartoon of a cramped Seoul businessman watching enviously as a Chinese rival pedals across the expanse of Beijing's Tiananmen Square on his bicycle. The caption read: "Ten reasons why foreign companies choose Beijing rather than Seoul."»--"South Korea to move capital 100 miles south: Rural region will become huge building site for new city"
Seoul had the worst standard of living among the world's 20 biggest cities
So maybe Seoul is the 20th biggest city, and maybe the 20 biggest cities are the 20 best cities to live in in the world, and Seoul is the 20th.
(Yeah, I know, that's not the case, but the statistic itself is still meaningless.)
