用北京2环到6环的地图衡量世界各大城市，非常直观哦。点击可以看更清晰的大图。
We made comparisons between Beijing & world's major cities by using five ring roads. Here we got very impressive resutls. Click the thumbs to see the full size pictures.
Beijing, China -- 北京，中国
5 red rings on behalf of the Beijing five loops: the Second Ring Road, the Third Ring Road, the Fourth Ring Road, the Fifth Ring Road & the Sixth Ring Road.
图上的5个圆环代表着北京的5个环路，分别是二环，三环，四环，五环，六环。
San Francisco VS Beijing -- 旧金山，美国
Los Angeles VS Beijing -- 洛杉矶，美国
New York VS Beijing -- 纽约，美国
Washington VS Beijing -- 华盛顿，美国
Tokyo VS Beijing -- 东京，日本
Seoul VS Beijing -- 首尔，韩国
London VS Beijing -- 伦敦，英国
Moscow VS Beijing -- 莫斯科，俄罗斯
Sydney VS Beijing -- 悉尼，澳大利亚
Melbourne VS Beijing -- 墨尔本，澳大利亚
New Delhi VS Beijing -- 新德里，印度
Hong Kong VS Beijing -- 香港，中国
Singapore VS Beijing -- 新加坡
Shanghai VS Beijing -- 上海，中国
Taipei VS Beijing -- 台北，中国
我觉得这些图有一些小问题，应该把其它城市的边界也标出来，这样才合理。
哈哈 好主意
I think it would be more appealing if the title is "How big is Beijing, comparing with other major cities in the world" .
Good point. I agree. I'm not English native. Thanks for your suggestion.
有创意
哈哈 我也觉得一目了然 很好玩
very clever idea! i've never seen this kind of comparison before.
+1.
never seen this comparison elsewhere. very creative invention indeed.
I think this is the nature of development of civilisation.
Things always surround the governing centers and rings of road extend outwards.
I guess that's of business and people start to congregate in the early days of development.
Absolutely. But people in the city center will be very crowded and the life inside is not good at all.
This is very interesting. Here are a few other cities that also would be interesting to compare - Mexico City, Dallas/Ft Woth, Twin Cities, Berlin and Paris
Bravo! Very impressive. Good job!
Very Impressive!
