"Vietnam's capital city is Hanoi. Approximately 85 miles (140 km) inland from the South China Sea, the city is located in northern Vietnam on the western bank of the Red River. Hanoi is not just the capital of the country but also a province-level municipality (thanh pho) that is run by the national government. 1,205 square miles (3,120 square kilometers) is the total area. A city's population was 1,523,936 in 1999; 5,053,654 in the municipality; 2,316,722 in 2009; 6,451,909 in the municipality; and 3,292,000 in the city as of 2014. Hanoi and Ho Chi Minh City will rank among the world's fastest-growing cities in terms of GDP growth between 2008 and 2025, citing a new PricewaterhouseCoopers ranking.[99] Hanoi made up 17% of the national budget, generated 12.6% of the GDP, exported 7.5% of all exports, and drew in 22% of Vietnam's investment capital in 2013. With a nominal GDP of 451,213 billion VND (US$21.48 billion) at current prices, the city's GDP per capita was 63.3 million VND (US$3,000) in 2013. Another robust area of the city is trade. With relations to 161 nations and territories, Hanoi had 2,000 companies involved in international trade in 2003. Between 1996 and 2000, the city's export value increased by 11.6 percent year on average, and between 2001 and 2003, it increased by 9.1 percent. Significant changes also occurred in the economic structure, with banking, finance, and tourism now playing a bigger part. Another robust area of the city is trade.

The first Western-style universities in Indochina were established in Hanoi, the capital of French Indochina. These included École Supérieure des Beaux-Arts de l'Indochina (1925), which is now Vietnam University of Fine Art (VNUFA) in Hanoi, Indochina Medical College (1902), which is now Hanoi Medical University (HMU), and Indochina University (1904), which is now the largest of the country's universities, Vietnam National University (VNU) in Hanoi. Noi Bai International Airport, situated in Soc Son District, around 15 km (9 km) north of Hanoi, serves the city. The airport underwent a significant makeover with the opening of the new international terminal (T2), which was created and constructed by Japanese contractors and inaugurated in January 2015. Additionally, the airport and city center are now connected by the new Nhat Tan cable-stay bridge and a new roadway, which opened simultaneously and provide far greater convenience than the previous route (via Thang Long bridge). Though it's also traditional to settle on the trip fee before taking a cab from the airport to the city center, taxis are frequent and typically have meters. Six national railway lines, totaling 162 km (101 mi) in length, pass through Hanoi, making it the starting or finishing location for many of the country's Vietnam Railways train routes.From Hanoi station (previously Hang Co station), the Reunification Express (tàu Thống Nhất) travels to Ho Chi Minh City, stopping at cities and provinces en route. Additionally, trains regularly leave Hanoi for Hai Phong and other northern locations. The city of Hanoi is home to numerous stadiums and gymnasiums. The most favored ones are Quần Ngựa Sports Palace (Văn Cao Avenue), Hanoi Aquatics Sports Complex, Hanoi Indoor Games Gymnasium, and Mỹ Đình National Stadium (Lê Đức Thọ Boulevard). The others are Thanh Trì Stadium, Hàng Đẫy Stadium, and Hà Đông Stadium. In 2009, Hanoi hosted the third Asian Indoor Games. The others are Vạn Bảo Sports Complex, Trịnh Hoài Đức Gymnasium, and Hai Bà Trưng Gymnasium. Several of these locations had activities during the Hanoi-hosted SEA Games in 2003 and 2021."

Cairo isn’t just the capital of Egypt — it’s the pulse of the nation. A city where ancient history meets modern chaos, where the call to prayer rises above the traffic, and where every alley seems to hum with life. Home to over 10 million people, Cairo is one of the biggest and most energetic cities in the Middle East and Africa. It’s a place of contrasts — the timeless Pyramids of Giza just a short drive from bustling markets, rooftop cafés, and shiny new malls. The Greater Cairo Metropolitan Area, with more than 22 million residents, is among the most populated urban regions on Earth. Surrounded by ancient sites like Memphis, Heliopolis, and the Giza Plateau, Cairo is a living bridge between Egypt’s past and its future. The city’s origins trace back to Fustat, Egypt’s first Islamic capital founded in 641 CE, and later to 969 CE, when the Fatimid dynasty created what we now call Cairo. Through centuries — under the Ayyubids, Mamluks, and beyond — the city became Egypt’s heart of architecture, art, and learning.
