Analogy to China: China has a large population, and its population of 6.3 million can only rank 56th in China, between Wuxi (637) and Nanchong (627); In terms of area, most cities in China have undergone great transformation, and there are actually a lot of non-urban land in the administrative area. China ranks 36th with 1255, which is more than Hong Kong (11kloc-0/) and worse than Xiamen (1638). When the GDP is converted from USD to RMB, the RMB against USD in 2000 is still 1:8.27- 1:8.28, the GDP of Rio is about 68 1 100 million yuan, and the per capita income is 47,450 yuan. In 2000, Shanghai, the largest city in China, had a GDP of 4551100 million yuan, with one Rio topping one and a half Shanghai. In 2000, the per capita GDP of China was higher than that of Rio de Janeiro in only seven places: Shenzhen, Daqing, Zhuhai, Yuxi, Dongying, Karamay and Panjin. Only Shenzhen and Zhuhai are really abundant, and the other five are all mines, so we can't count them, while Guangzhou (38568) and Hangzhou (38247) are less than Rio de Janeiro.
