Why Visit Shanghai: The Argument for China's Megacity

Shanghai operates at a scale that resists comparison. The municipality contains 24.87 million registered residents as of the 2020 census, occupying 6,340 square kilometers where the Yangtze River meets the East China Sea. This is not a city that grew organically over millennia but one that was engineered into existence beginning in 1843 when the Treaty of Nanking opened it as a treaty port. What existed before was a modest fishing and textile town. What exists now is the world's busiest container port by volume, processing 47.03 million twenty-foot equivalent units in 2021 according to port authority records, and a financial district in Pudong that houses the Shanghai Stock Exchange with a market capitalization exceeding 7 trillion USD as of late 2023.

The architecture tells the story of jurisdictional fragmentation frozen in stone and steel. The International Settlement covered 8.66 square miles by 1899, governed by the Shanghai Municipal Council representing British, American, and later other foreign interests. The French Concession operated under separate administration from 1849 until 1943, leaving behind 31 square kilometers of tree-lined streets and low-rise buildings that now form the city's most photographed residential zones. The Bund stretches 1.5 kilometers along the western bank of the Huangpu River, with 52 buildings constructed primarily between 1920 and 1937 in styles ranging from Gothic Revival to Art Deco, housing the former headquarters of HSBC, the Customs House with its 13.7-meter clock tower modeled on Big Ben, and the Peace Hotel completed in 1929. Across the river, Pudong was farmland until the State Council designated it a Special Economic Zone in 1990. The Shanghai Tower opened in 2015 reaching 632 meters across 128 floors, making it the tallest building in China and the third tallest structure globally. The Jin Mao Tower stands at 420.5 meters with 88 floors completed in 1999. The Shanghai World Financial Center reaches 492 meters and opened in 2008. These three buildings stand within a 500-meter radius.

The metro system began operation in 1993 with a single 16.1-kilometer line. As of 2024, Shanghai Metro operates 20 lines covering 831 kilometers with 508 stations, making it the longest metro network by route length globally according to operator records. Daily ridership averages 11 million passengers on weekdays. Line 11 extends 82.4 kilometers from Jiading North to Disney Resort, the longest single metro line by distance in the world. The Maglev train connects Pudong International Airport to Longyang Road station, covering 30.5 kilometers in 8 minutes at operational speeds of 431 kilometers per hour, the fastest commercial train service in regular operation globally. Pudong International Airport handled 76.15 million passengers in 2019 before pandemic disruption, ranking it ninth globally that year. Hongqiao International Airport, the older facility, processed an additional 45.43 million passengers the same year.

The port dominates global container logistics. Shanghai Port includes facilities along both banks of the Huangpu River and the Yangtze River Estuary, but the majority of deep-water capacity sits at Yangshan Deep Water Port, constructed on the Yangshan Islands 32 kilometers offshore in Hangzhou Bay. The port began operation in 2005 and expanded to become the world's largest automated container terminal. The Donghai Bridge connects Yangshan to the mainland, spanning 32.5 kilometers and ranking among the longest cross-sea bridges globally when it opened in 2005. The port handles vessels with drafts up to 16 meters, allowing it to accommodate the largest container ships afloat.

The financial sector concentration is documented in regulatory filings. The Shanghai Stock Exchange lists more than 2,100 companies. The China Foreign Exchange Trade System, which sets the daily central parity rate for the yuan, operates from Shanghai. The Shanghai Gold Exchange, established in 2002, is the only institution in China approved to carry out physical gold trading. The Shanghai International Energy Exchange launched yuan-denominated crude oil futures in 2018. The headquarters of the People's Bank of China's Shanghai Head Office coordinates monetary policy implementation across the Yangtze Delta. More than 900 financial institutions maintain operations in the city according to municipal government records.

The Yangtze River Delta urban cluster, defined by the National Development and Reform Commission, includes Shanghai plus 26 cities across Jiangsu, Zhejiang, and Anhui provinces, covering 211,700 square kilometers with a combined population exceeding 235 million as of 2020. This region generates approximately 24 percent of China's GDP on 2.2 percent of its land area. Shanghai functions as the administrative and financial nucleus. High-speed rail connects Shanghai Hongqiao Railway Station to Hangzhou in 45 minutes, to Suzhou in 25 minutes, and to Nanjing in 1 hour 10 minutes on trains traveling at 350 kilometers per hour. Hangzhou sits 175 kilometers southwest. Suzhou lies 100 kilometers northwest. Nanjing is 300 kilometers upriver. These are not satellite cities but integrated components of a polycentric megalopolis with specialized industrial and cultural functions.

Shanghai's status as a treaty port created a unique legal and social environment that persisted until 1943. The Mixed Court in the International Settlement operated under Chinese judges but with foreign consular oversight for cases involving foreign nationals. The French Concession maintained its own police force, the Police Municipal, with French officers commanding Chinese rank and file. The Shanghai Municipal Council collected taxes, maintained roads, operated utilities, and enforced building codes within the Settlement. This resulted in infrastructure investment patterns that diverged sharply from the rest of China. By 1935, the International Settlement had a sewage system serving 80 percent of the population, electricity supply to 95 percent of buildings, and a running water network covering the entire settlement. The city became China's publishing center with more than 300 newspapers operating in the 1930s. The film industry produced roughly 500 films between 1931 and 1937, most shot in studios in the International Settlement and French Concession.

The Battle of Shanghai began on August 13, 1937, and continued until November 26, 1937, involving more than one million combatants and resulting in estimates of 200,000 to 300,000 casualties across both sides and civilian populations. The fighting destroyed entire neighborhoods outside the foreign settlements. The foreign concessions remained neutral territory until December 1941, creating an unusual refuge status that allowed continued commercial and cultural activity while the surrounding regions experienced wartime conditions. The International Settlement and French Concession ceased to exist on July 30, 1943, when the Wang Jingwei regime formally ended extraterritorial rights.

Manufacturing remains central despite the shift toward services. The Shanghai Automotive Industry Corporation produces vehicles under joint ventures with Volkswagen and General Motors, manufacturing over 5 million vehicles annually across its facilities. The Jiangnan Shipyard, founded in 1865, builds naval vessels and commercial ships at its Changxing Island facility. Shanghai accounts for roughly 12 percent of China's semiconductor production according to industry association data. The Zhangjiang Hi-Tech Park in Pudong hosts more than 900 companies in pharmaceuticals, biotechnology, and integrated circuits.

The Classical Gardens of Suzhou lie 100 kilometers northwest, easily reached in under 30 minutes by high-speed rail. Nine gardens achieved UNESCO World Heritage inscription in 1997 and 2000. The Humble Administrator's Garden covers 5.2 hectares designed during the Ming Dynasty in 1509. The Lingering Garden dates to 1593. These are not parks but constructed landscapes integrating buildings, ponds, rock formations, and plantings according to principles documented in texts like the Yuan ye, the earliest Chinese treatise on garden design published in 1634. Tongli, Zhouzhuang, Xitang, and Wuzhen water towns preserve residential architecture from the Ming and Qing dynasties built along canal networks that connected to the Grand Canal. These towns functioned as trade nodes in the textile and grain distribution systems. Zhouzhuang has 14 stone bridges dating from the Song to Qing dynasties across 0.47 square kilometers. Tongli contains 49 bridges across its canal network.

Hangzhou sits at the southern terminus of the Grand Canal, which runs 1,776 kilometers from Hangzhou to Beijing, making it the longest artificial waterway globally. West Lake covers 6.5 square kilometers surrounded by hills on three sides. The lake is entirely artificial, created during the Tang Dynasty through systematic dredging and dike construction. The causeways dividing the lake into five sections were built in the 9th and 11th centuries. The lake achieved UNESCO inscription in 2011 as the West Lake Cultural Landscape based on its influence on garden design theory across East Asia documented in treatises and poetry. The Lingyin Temple, founded in 326 CE, sits 2 kilometers west of the lake and contains the Hall of the Great Hero reconstructed in 1956 based on Qing Dynasty designs, standing 33.6 meters tall and housing a 19.6-meter seated Buddha carved from camphor wood.

Nanjing served as the capital of six dynasties between 229 and 589 CE, then again as the Ming Dynasty capital from 1368 to 1421 before the court moved to Beijing. The Nanjing City Wall, constructed between 1366 and 1393, originally ran 35.3 kilometers with 13 gates and remains the longest city wall globally built as a unified project. Approximately 25 kilometers of the wall survives intact. The wall reaches heights of 14 to 21 meters with a base thickness of 14 meters. More than 350,000 laborers worked on the construction, and each brick bears the name of the work unit that produced it, creating accountability that is still legible today. The Sun Yat-sen Mausoleum, completed in 1929, sits at the foot of Purple Mountain and required climbing 392 steps to reach the burial chamber containing the marble sarcophagus.

Chongming Island sits in the Yangtze River Estuary covering 1,200 square kilometers, the largest alluvial island in the world formed by Yangtze sediment deposition over approximately 1,400 years. The island is expanding eastward at roughly 150 meters per year as sediment continues to accumulate. The Chongming Dongtan Nature Reserve protects 241.55 square kilometers of tidal mudflats and wetlands, serving as habitat for more than 160 bird species during spring and autumn migrations along the East Asian-Australasian Flyway. The reserve recorded counts of more than 100,000 migratory waterfowl during peak seasons according to reserve monitoring data.

The Shanghai hairy crab refers specifically to Eriocheir sinensis harvested from Yangcheng Lake near Kunshan, though the majority of commercial production now comes from aquaculture facilities across Jiangsu. The crabs are consumed from October through December when they reach sexual maturity. Authentic Yangcheng Lake crabs are tagged and sold at prices reaching 300 to 800 yuan per kilogram based on size and gender. Xiaolongbao originated in Nanxiang, a town now incorporated into Shanghai's Jiading District, during the Tongzhi reign of the Qing Dynasty around 1871. The buns contain a minimum of 18 pleats in traditional preparation, with the soup interior created by incorporating aspic that liquefies during steaming. Dongpo pork, named for Song Dynasty poet Su Dongpo who served as governor of Hangzhou, involves braising pork belly in soy sauce, rice wine, ginger, and rock sugar for over 2 hours until the fat renders translucent.

The Shanghai World Expo ran from May 1 to October 31, 2010, on a 5.28-square-kilometer site along both banks of the Huangpu River in Pudong. The expo recorded 73.08 million visitors, the highest attendance of any World Expo according to Bureau International des Expositions records. One hundred ninety-two countries and 50 international organizations participated. The China Pavilion, designed as an inverted pyramid reaching 63 meters in height and painted vermilion, became a permanent structure after the expo closed. The Mercedes-Benz Arena, built as the expo performance center, operates as an 18,000-seat indoor venue.

Lu Xun lived in Shanghai from 1927 until his death in 1936, residing in Hongkou District and writing works including "The True Story of Ah Q" while evading Kuomintang surveillance. His former residence on Shanyin Road is preserved as a museum. Soong Ching-ling, wife of Sun Yat-sen, was born in Shanghai in 1893 and maintained a residence on Huaihai Road that now functions as a museum containing original furnishings from her occupancy between 1948 and 1963. I.M. Pei was born in Guangzhou in 1917 but spent his childhood in Shanghai and Hong Kong before moving to the United States in 1935, later designing the Bank of China Tower in Hong Kong completed in 1990 and the Suzhou Museum completed in 2006.

The Jade Buddha Temple houses two jade Buddha statues brought from Myanmar in 1882, the seated Buddha measuring 1.95 meters in height and weighing approximately 3 tons, carved from a single piece of white jade. The Longhua Temple, founded in 242 CE, contains a seven-story pagoda standing 40.4 meters tall, rebuilt during the Song Dynasty around 977 CE using brick and wood construction. Jing'an Temple, originally built in 247 CE, was relocated to its current site in 1216 and reconstructed most recently between 1983 and 2010 after complete destruction during the Cultural Revolution.

Shanghai Pudong International Airport began operation on October 1, 1999, with two parallel runways and a single terminal. The airport has since expanded to four terminals and five runways, with a sixth runway under construction. Terminal 1 covers 280,000 square meters. Terminal 2, opened in 2008, adds 480,000 square meters. The Satellite Concourse, opened in 2019, provides an additional 620,000 square meters connected to Terminal 1 and Terminal 2 via automated people movers traveling in underground tunnels. The airport operates 24 hours with no curfew restrictions.

The argument for Shanghai is empirical: it is where the greatest concentration of infrastructure, capital, manufacturing capacity, and logistical connectivity exists within the Yangtze Delta region, functioning as the primary interface between China's interior and global maritime trade networks.
