Pearl River Delta in the context of Port of Guangzhou

A megalopolis (/ˌmɛɡəˈlɒpəlɪs/), also called a supercity or megaregion, is a group of metropolitan areas which are perceived as a continuous urban area through common systems of transport, economy, resources, ecology, and so on. They are integrated enough that coordinating policy is valuable, although the constituent metropolises keep their individual identities. The megalopolis concept has become highly influential as it introduced a new, larger scale thinking about urban patterns and growth.

Cantonese is the traditional prestige variety of Yue Chinese, a Sinitic language belonging to the Sino-Tibetan language family. It originated in the city of Guangzhou (formerly romanized as Canton) and its surrounding Pearl River Delta. Although Cantonese specifically refers to the prestige variety in linguistics, the term is often used more broadly to describe the entire Yue subgroup of Chinese, including varieties such as Taishanese, which have limited mutual intelligibility with Cantonese.

Cantonese is viewed as a vital and inseparable part of the cultural identity for its native speakers across large swaths of southeastern China, Hong Kong, and Macau, as well as in overseas communities. In mainland China, it is the lingua franca of the province of Guangdong (being the majority language of the Pearl River Delta) and neighbouring areas such as Guangxi. It is also the dominant and co-official language of Hong Kong and Macau. Further, Cantonese is widely spoken among overseas Chinese in Southeast Asia (most notably in Vietnam and Malaysia, as well as in Singapore and Cambodia to a lesser extent) and the Western world. With about 80 million total speakers as of 2023, standard Cantonese is by far the most spoken variant of Yue Chinese and non-Mandarin Chinese language.

Zhuhai is a resort city located on the west bank of the Pearl River estuary, near Macau on the central coast of southern Guangdong, China, on the southeastern edge of the Pearl River Delta. Its name literally means "pearl sea", which originates from the city's location at the mouth of the Pearl River meeting the South China Sea. Zhuhai borders Jiangmen to the west, Zhongshan to the north and Macau to the southeast, and has a bridge connecting to Hong Kong.

Zhuhai was one of the original four Special Economic Zones established in 1980, as well as one of China's premier tourist destinations, being called the Chinese Riviera. While the city is located in the traditionally Cantonese-speaking province of Guangdong, a significant portion of the population is now made up of Mandarin-speaking economic migrants originally from inland provinces.

The Jing-Jin-Ji cluster is an expanded urban agglomeration consisting of Beijing (Jing), Tianjin (Jin), and Hebei (Ji). It is the biggest urban agglomeration region in North China, including an economic region surrounding the municipalities of Beijing and Tianjin, and along the coast of the Bohai Sea. This emerging region is rising as a northern metropolitan region rivaling the Pearl River Delta in the south and the Yangtze River Delta in the east. In 2020, it had a total population of 110 million people, comparable to that of the Philippines.

Dongguan is a prefecture-level city in central Guangdong Province, China. An important industrial city in the Pearl River Delta, Dongguan borders the provincial capital of Guangzhou to the north, Huizhou to the northeast, Shenzhen to the south, and the Pearl River to the west. It is part of the Pearl River Delta built-up (or metro) area with more than 65.57 million inhabitants as of the 2020 census spread over nine municipalities across an area of 19,870 square kilometers (7,670 sq mi).

Dongguan's city administration is considered especially progressive in seeking foreign direct investment. Dongguan ranks behind only Shenzhen, Shanghai and Suzhou in exports among Chinese cities, with $65.54 billion in shipments. It is also home to one of the world's largest shopping malls, the New South China Mall, which is seeing increased activity. Although the city is geographically and thus culturally Cantonese in the Weitou form and as well as culturally Hakka in the prefectures of Fenggang and Qingxi, the majority of the modern-day population speaks Mandarin due to the large influx of economic migrants from other parts of China. The city is home to several universities, including Guangdong University of Science and Technology, Guangdong Medical University and Dongguan University of Technology.

The Bohai Economic Rim (BER) or Bohai Bay Economic Rim (BBER) is the economic region surrounding Tianjin (Tientsin). It also includes areas in Hebei, Liaoning and Shandong surrounding the Bohai Sea. This region has undergone major economic and infrastructural changes and is an emerging economic powerhouse of North China, rivaling both the Pearl River Delta in southern China and the Yangtze River Delta in eastern China.

The Daxi culture (5000–3300 BC) was a Neolithic culture centered in the Three Gorges region around the middle Yangtze, China. The culture ranged from western Hubei to eastern Sichuan and the Pearl River Delta. The site at Daxi, located in the Qutang Gorge around Wushan, Chongqing, was discovered by Nels C. Nelson in the 1920s.

Kongsi (Chinese: 公司; Pe̍h-ōe-jī: kong-si; pinyin: gōngsī; Jyutping: gung1 si1) is a Hokkien transcription of a Chinese term meaning "company", especially businesses which have been incorporated. However, the word has other meanings under different historical contexts. Kongsi were most commonly known as Chinese social organizations or partnerships, but the term was also used for various Chinese institutions.

Amongst overseas Chinese, the word kongsi was applied to reference both clan organizations, whose members shared a common descent, and to district-dialect clubs, for Chinese immigrants originating from the same district speaking the same dialect. In the late 19th century, these district-dialect associations came to be known as wui gun (huiguan; traditional Chinese: 會館; simplified Chinese: 会馆; Jyutping: wuigun; pinyin: huìguǎn), especially in San Francisco, California where many Chinese from eight districts on the west side of the Pearl River Delta near the City of Canton went for the California gold rush.

Taishanese (simplified Chinese: 台山话; traditional Chinese: 臺山話; pinyin: Táishān huà; Jyutping: toi4 saan1 waa2), alternatively romanized in Cantonese as Toishanese or Toisanese, in local dialect as Hoisanese or Hoisanwa, is a Yue Chinese language native to Taishan, Guangdong.

Even though they are related, Taishanese has little mutual intelligibility with Cantonese. It is not a dialect of Cantonese. Taishanese is also spoken throughout Sze Yup (or Siyi in the pinyin romanization of Standard Mandarin Chinese), located on the western fringe of the Pearl River Delta in Guangdong, China. In the late 19th century and early 20th century, most of the Chinese emigration to North America originated in Sze Yup (which includes Taishan). Thus, up to the mid-20th century, Taishanese was the dominant variety of the Chinese language spoken in Chinatowns in Canada and the United States. It was formerly the lingua franca of the overseas Chinese residing in the United States.

The Pearl River (Chinese: 珠江; pinyin: Zhūjiāng; lit. 'pearl river', or 粤江; 粵江; Yuèjiāng; 'Yue river') is an extensive river system in southern China. "Pearl River" is often also used as a catch-all for the watersheds of the Pearl tributaries within Guangdong, specifically the Xi ('west'), Bei ('north'), and Dong ('east'). These rivers all ultimately flow into the South China Sea through the Pearl River Delta. Measured from the farthest reaches of the Xi River, the Pearl–Xi–Xun–Qian–Hongshui–Nanpan 2,400 km (1,500 mi) Pearl River system constitutes China's third-longest, after the Yangtze River and the Yellow River, and its second largest by volume, after the Yangtze. The 453,700 km (175,200 sq mi) Pearl River Basin drains the majority of Guangdong and Guangxi provinces (collectively known as Liangguang), as well as parts of Yunnan, Guizhou, Hunan and Jiangxi; it also drains the northernmost parts of Vietnam's Northeast Cao Bằng and Lạng Sơn provinces. The Pearl River is famed as the river that flows through Guangzhou.

As well as referring to the system as a whole, the Pearl River name is applied to a specific branch within it. This Pearl River is the widest distributary within the delta, although notably short; the waters that converge east of the Bei are first referred to as the Pearl River just north of Guangzhou. The Pearl River's estuary, Bocca Tigris, is regularly dredged so as to keep it open for ocean vessels. The mouth of the Pearl River forms a large bay in the southeast of the delta, the Pearl River Estuary, the Bocca Tigris separates Shiziyang in the north, Lingdingyang in the south, and Jiuzhouyang at the southern tip of the estuary surrounded by the Wanshan Archipelago. This bay separates Macau and Zhuhai from Hong Kong and Shenzhen.

The Guangdong–Hong Kong–Macao Greater Bay Area, commonly referred to as the Greater Bay Area (GBA), is a megalopolis, consisting of nine cities and two special administrative regions in South China. It is envisioned by Chinese government planners as an integrated economic area aimed at taking a leading role globally by 2035.

It is the largest and most populated urban area in the world. The GBA—with a total population of approximately 86 million people—includes nine mega cities of Guangdong province: Guangzhou, Shenzhen, Zhuhai, Foshan, Dongguan, Zhongshan, Jiangmen, Huizhou, and Zhaoqing as well as two special administrative regions, Hong Kong, and Macao (Macau). Hong Kong, Guangzhou, and Shenzhen have been described among the world's 50 "superstar cities". Surrounding the Pearl River Delta with a total area of 56,000 km (comparable in size to Croatia), it is the largest and the richest economic region in South China.

The Pearl River Delta Economic Zone (simplified Chinese: 珠江三角洲经济区; traditional Chinese: 珠江三角洲經濟區; pinyin: Zhūjiāng Sānjiǎozhōu Jīngjìqū) is a special economic zone on the southeastern coast of China. Located in the Pearl River Delta, it consists of the Chinese cities of Guangzhou, Shenzhen, Zhuhai, Foshan, Dongguan, Zhongshan, Jiangmen, and parts of Huizhou and Zhaoqing. Adjacent Hong Kong and Macau are not part of the economic zone.

The 2008-20 plan, released by China's National Development and Reform Commission, was supposed to be designed to boost the pan-Pearl River Delta as a "center of advanced manufacturing and modern service industries", and as a "center for international shipping, logistics, trade, conferences and exhibitions and tourism". Goals included the development of two to three new cities in the Guangdong-Hong Kong-Macao Greater Bay Area, the development of 10 new multinational firms, and expansion of road, rail, seaport and airport capacities by 2020. They included construction of the 31-mile (50 km) Hong Kong–Zhuhai–Macau Bridge linking Hong Kong, Macau, and the Pearl River Delta. The construction of 1,864 miles (3,000 km) of highways in the region was to be completed by 2012, and rail expansions of 683 miles (1,099 km) by 2012 and 1,367 miles (2,200 km) by 2020.

The Port of Shenzhen is the collective name of a number of ports the coastline of Shenzhen, Guangdong Province, China. These ports as a whole form one of the busiest and fastest growing container ports in the world.

The port is home to 40 shipping companies who have launched around 130 international container routes. There are 560 ships on call at Shenzhen port on a monthly basis and also 21 feeder routes to other ports in the Pearl River Delta region. The Shekou Cruise Center provides ferry services across the Pearl River Delta to places such as Hong Kong, Macau, and Zhuhai; it replaced the Shekou Passenger Terminal in 2016.

The Second Battle of Chuenpi (Chinese: 第二次穿鼻之戰) was fought between British and Chinese forces in the Pearl River Delta, Guangdong province, China, on 7 January 1841 during the First Opium War. The British launched an amphibious attack at the Humen strait (Bogue), capturing the forts on the islands of Chuenpi and Taikoktow. Subsequent negotiations between British Plenipotentiary Charles Elliot and Chinese Imperial Commissioner Qishan resulted in the Convention of Chuenpi on 20 January. As one of the terms of the agreement, Elliot announced the cession of Hong Kong Island to the British Empire, after which the British took formal possession of the island on 26 January.

The Cantonese people (廣府人; 广府人; gwong2 fu2 jan4; Gwóngfú Yàhn) or Yue people (粵人; 粤人; jyut6 jan4; Yuht Yàhn), are a Han Chinese subgroup originating from Guangzhou and its satellite cities and towns (as well as Hong Kong and Macau), who natively speak the Cantonese language. In a more general sense, "Cantonese people" can refer to any Han Chinese originating from or residing in the provinces of Guangdong and Guangxi (collectively known as Liangguang), or it may refer to the inhabitants of Guangdong province alone.

Historically centered around Guangzhou and the surrounding Pearl River Delta, the Cantonese people established the Cantonese language as the dominant one in Hong Kong and Macau during their 19th century migrations within the times of the British and Portuguese colonial eras respectively. Cantonese remains today as a majority language in Guangdong and Guangxi, despite the increasing influence of Mandarin.
