Philadelphia, colloquially Philly, is the largest city in the U.S. state of Pennsylvania and the sixth-most populous U.S. city, with a 2019 estimated population of 1,584,064. Since 1854, the city has had the same geographic boundaries as Philadelphia County, the most-populous county in Pennsylvania and the urban core of the eighth-largest U.S. metropolitan statistical area, with over 6 million residents as of 2017. Philadelphia is also the economic and cultural center of the greater Delaware Valley along the lower Delaware and Schuylkill rivers within the Northeast megalopolis. The Delaware Valley's population of 7.2 million makes it the eighth-largest combined statistical area in the United States.Philadelphia is one of the oldest municipalities in the United States. William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 at the Second Continental Congress, and the Constitution at the Philadelphia Convention of 1787. Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress, the preservation of the Liberty Bell, the Battle of Germantown, and the Siege of Fort Mifflin. Philadelphia remained the nation's largest city until being overtaken by New York City in 1790; the city was also one of the nation's capitals during the revolution, serving as temporary U.S. capital while Washington, D.C. was under construction. In the 19th and 20th centuries, Philadelphia became a major industrial center and a railroad hub. The city grew due to an influx of European immigrants, most of whom initially came from Ireland and Germany—the two largest reported ancestry groups in the city as of 2015. Later immigrant groups in the 20th century came from Italy (Italian being the third largest European ethnic ancestry currently reported in Philadelphia) and other Southern European and Eastern European countries.

In the early 20th century, Philadelphia became a prime destination for African Americans during the Great Migration after the Civil War. Puerto Ricans began moving to the city in large numbers in the period between World War I and II, and in even greater numbers in the post-war period. The city's population doubled from one million to two million people between 1890 and 1950. The Philadelphia area's many universities and colleges make it a top study destination, as the city has evolved into an educational and economic hub. As of 2019, the Philadelphia metropolitan area is estimated to produce a gross metropolitan product (GMP) of $490 billion. Philadelphia is the center of economic activity in Pennsylvania and is home to five Fortune 1000 companies. The Philadelphia skyline is expanding, with a market of almost 81,900 commercial properties in 2016, including several nationally prominent skyscrapers. Philadelphia has more outdoor sculptures and murals than any other American city. Fairmount Park, when combined with the adjacent Wissahickon Valley Park in the same watershed, is one of the largest contiguous urban park areas in the United States. The city is known for its arts, culture, cuisine, and colonial history, attracting 42 million domestic tourists in 2016 who spent $6.8 billion, generating an estimated $11 billion in total economic impact in the city and surrounding four counties of Pennsylvania. Philadelphia has also emerged as a biotechnology hub.Philadelphia is the home of many U.S. firsts, including the first library (1731), hospital (1751), medical school (1765), national capital (1774), stock exchange (1790), zoo (1874), and business school (1881). Philadelphia contains 67 National Historic Landmarks and the World Heritage Site of Independence Hall. The city became a member of the Organization of World Heritage Cities in 2015, as the first World Heritage City in the United States.

Guangzhou (; simplified Chinese: 广州; traditional Chinese: 廣州, Cantonese pronunciation: [kʷɔ̌ːŋ.tsɐ̂u] or [kʷɔ̌ːŋ.tsɐ́u] (listen); Mandarin pronunciation: [kwàŋ.ʈʂóu] (listen)), also known as Canton and formerly romanized as Kwangchow, is the capital and most populous city of the province of Guangdong in southern China. On the Pearl River about 120 km (75 mi) north-northwest of Hong Kong and 145 km (90 mi) north of Macau, Guangzhou has a history of over 2,200 years and was a major terminus of the maritime Silk Road, and continues to serve as a major port and transportation hub, as well as one of China's three largest cities.Guangzhou is at the heart of the most-populous built-up metropolitan area in mainland China, which extends into the neighboring cities of Foshan, Dongguan, Zhongshan and Shenzhen, forming one of the largest urban agglomerations on Earth, the Pearl River Delta Economic Zone. Administratively, the city holds subprovincial status and is one of China's nine National Central Cities. At the end of 2018, the population of the city's expansive administrative area was estimated at 14,904,400 by city authorities, up 3.8% from the previous year. Guangzhou is highly ranked as an Alpha- (global first-tier) city together with Melbourne (Australia), San Francisco (the U.S), and Stockholm (Sweden). Guangzhou also ranks 21st globally (between Washington, D.C. and Amsterdam) and 8th in Asia (behind Shanghai, Tokyo, Hong Kong, Singapore, Beijing, Shenzhen and Dubai) in the 2020 Global Financial Centers Index (GFCI). There is a rapidly increasing number of foreign temporary residents and immigrants from Southeast Asia, the Middle East, Eastern Europe and Africa.

This recent population influx has led to it being dubbed the "Capital of the Third World".The domestic migrant population from other provinces of China in Guangzhou was 40% of the city's total population in 2008. Together with Shanghai, Beijing and Shenzhen, Guangzhou has one of the most expensive real estate markets in China. In the late 1990s and early 2000s, nationals of sub-Saharan Africa who had initially settled in the Middle East and other parts of Southeast Asia moved in unprecedented numbers to Guangzhou in response to the 1997/98 Asian financial crisis.Long the only Chinese port accessible to most foreign traders, Guangzhou was captured by the British during the First Opium War. No longer enjoying a monopoly after the war, it lost trade to other ports such as Hong Kong and Shanghai, but continued to serve as a major transshipment port. Nowadays, in modern commerce, Guangzhou is best known for its annual Canton Fair, the oldest and largest trade fair in China. For three consecutive years (2013–2015), Forbes ranked Guangzhou as the best commercial city in mainland China.The city is home to multiple China's prestigious universities, including Sun Yat-sen University, South China University of Technology, South China Normal University and Jinan University. Guangzhou is also one of the top city in the world by scientific research as tracked by the Nature Index and it ranks 15th globally and fifth in China (after Beijing, Shanghai, Nanjing and Wuhan).
