The United States has always occupied the position of world hegemony, and its economic level ranks first in the world. Since its inception, New China has developed very rapidly, and its gdp has surpassed Japan in 2010, second only to the United States. Chicago in the United States is the third largest city after New York and Los Angeles, and what are the advantages and disadvantages compared with Guangzhou, the third largest city in China?

First, Guangzhou has a beautiful geographical environment
The first is Guangzhou, which is located in southern China, one of the most economically developed cities in South China, in the north-central part of the Pearl River Delta, bordering the South China Sea, covering an area of 7434.4 square kilometers, across the sea from Hong Kong and Macao. As of 2020, Guangzhou has a population of 18.6766 million, is one of the five major national central cities, and is also an international business and trade center and comprehensive transportation hub approved by the State Council.
Guangzhou is the capital city of Guangdong Province, where the legend of five immortals riding five-colored sheep to bless the place, is also known as the Sheep City. Guangzhou belongs to the hilly area, the terrain is lowered from northeast to southwest, the highest peak is the heavenly peak in the north, 1210 meters above sea level, and the central part is the basin. Guangzhou is located in a low latitude region, the climate type belongs to the subtropical oceanic monsoon climate, the climate is pleasant, the average annual temperature is between 20 and 22 degrees, the temperature difference is very small, and the rainfall is abundant.
There are many rivers in Guangzhou, with vast waters, 1368 rivers with a width of more than 5 meters, with a total length of nearly 5600 kilometers. Because of the warm climate and sufficient rainfall, the plants have received very sufficient nutrients here, coupled with the government's great attention, Guangzhou's ecological environment is very beautiful, and the air pollution index has decreased year by year.
Guangzhou's geographical environment is very suitable for growing crops, and it is one of the most abundant fruit tree resources in the country, covering more than 500 varieties from tropical to temperate zones, as well as a variety of flowers and green plants, with the reputation of flower city. Guangzhou's rare mineral resources are not rich, mainly some granite, limestone, ceramic clay and other construction minerals.
The most famous building in Guangzhou is the Canton Tower, because of its unique shape of the thickness and thickness of the upper and lower thickness, also known as the small barbarian waist, which has a very good sense of design. Located near the Chigang Pagoda in Haizhu District, Guangzhou Tower is only 125 meters from the shore of the Pearl River, with a height of 600 meters and a total of 112 floors, making it the tallest tower in China and a national 4A-level scenic spot. The Tower is hollow overall, made up of 24 steel columns twisted counterclockwise from bottom to top, but it is very strong and is expected to withstand a magnitude 8 earthquake and a 12-magnitude typhoon.
In 2020, Guangzhou's regional GDP reached 2,501.911 billion yuan, an increase of 2.7% year-on-year. The largest proportion of Guangzhou's economic development is the modern service industry, followed by industry, and finally agriculture.
Second, one of the world's financial centers, Chicago's economic level is superior
Located in the heart of the North American continent, northeast of the U.S. state of Illinois, south of Michigan, Chicago is the third largest city in the United States after New York and Los Angeles, and one of the world's international financial centers, with a length of 40.23 kilometers from north to south, a width of 24.14 kilometers from east to west, covering an area of 606.2 square kilometers, and as of July 2018, the population here was 2.7059 million.
Unlike the hilly terrain of Guangdong, Chicago's terrain is very flat, belonging to the plain area, and the highest southern suburb is only 224 meters above sea level, so the urban architecture here is very regular, dividing the land into squares. Chicago is lined with high-rise buildings, the world's tallest office building Willis Tower towering here, the entire building is 527.3 meters high, a total of 110 floors, an area of 416,000 square meters. The Willis Tower is simple in shape and full of American architecture.
Chicago's climate type is temperate continental, with four distinct seasons, which is larger than the annual temperature difference in Guangzhou, with an average maximum temperature of 29 degrees in summer and an average minimum temperature of minus 11 degrees Celsius in winter. The precipitation here is not as large as in Guangzhou, but it is also abundant, mostly in the form of summer thunderstorms and winter snowfall.
Michigan Beard, the third largest of the Five Great Lakes in North America, gave birth to the city of Chicago, where the branch is known as the Chicago River, with a total length of 251 kilometers and a very large basin area of 674 square kilometers.
Chicago's mineral resources are rich in reserves, ranking first in the United States, mainly coal mines, oil, natural gas, etc., the level of industrial development here is very advanced, and the steel manufacturing industry is the first in the United States. In 2016, Chicago's regional GDP reached 537.3 billion US dollars, a total of 3590 billion yuan, Chicago's main economic source is developed industry and manufacturing, followed by tourism, about 2.5 million people visit the city every year, and finally agriculture, Chicago's geographical environment is very suitable for the development of agriculture, agricultural output value accounts for 10% of GDP.
Third, the two cities have their own advantages
In terms of economic development level, in 2020, Guangzhou's GDP was 2501.911 billion yuan, and in 2016, Chicago's regional GDP reached 3.59 trillion yuan, far more than Guangzhou's one trillion yuan, while Guangzhou's per capita GDP was 24,000 US dollars, and Chicago's was as high as 199,000 US dollars, a very large gap. Chicago's area is only 8% of Guangzhou's, and its population is only 14% of Guangzhou's, but there is such a big gap in the GDP of the two cities, it is clear that Chicago is far more economically advanced than Guangzhou.
In terms of people's lives, from 2018 to 2019, Guangzhou was selected as the happiest city in China, which was selected by the local citizens' sense of identity, belonging and stability and satisfaction of the city to which they belong, and it can be seen that guangzhou citizens live very happily. As of July 2021, Guangzhou has become an international sister city with 38 cities and reached friendly cooperation and exchange intentions with 53 other countries, making it a very inclusive city.
In 2018, british magazines interviewed a total of 15,000 residents in 32 cities according to multiple directions such as urban culture, resident friendliness, and living costs, and finally Chicago was selected as the best living city in the world, which shows that Chicago's living standards are also quite good.
Educationally, the University of Chicago is located in the Hyde Park area south of Chicago, 11 kilometers from the city center, covers an area of 217 acres, and the green environment on campus is excellent. As of October 2020, the University of Chicago has produced 100 Nobel Laureates, 10 Fields Medal winners and countless social elites, where the 44th President of the United States, Barack Obama, has taught constitutional law.
Sun Yat-sen University in Guangzhou is also a very famous university, belonging to the national 985, 211 project, as of May 2018, Guangdong University teachers and students have won a total of 26 national awards. Although it is slightly inferior to the University of Chicago in terms of awards, it has also attracted a lot of talents.
Objectively speaking, Guangzhou's current economic development is far from catching up with Chicago, but the land area and population are superior to Chicago, and today, when China's economic development is very rapid, I believe that Guangzhou will have its own side in the international world in the near future.
