Cantonese people in the context of Romanization of Cantonese

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.

Chinese people in Sri Lanka or Sri Lankan Chinese (Sinhala: ශ්‍රී ලාංකික චීන; Tamil: இலங்கை சீனர்கள்), are Sri Lankan citizens of full or partial Chinese descent born or raised in Sri Lanka. Most trace their origins to Hakka and Cantonese migrants from the southern coastal regions of China and other Han migrants from Hubei and Shandong who migrated to Sri Lanka in the 17th, 18th and 19th centuries.

Intermarriage between Sri Lankans, mostly Sinhalese women, and ethnic Chinese men is very common and they have adopted the culture, language and integrated into broader Sri Lankan society. As a result, the vast majority of Sri Lankan Chinese have partial Sinhalese ancestry. Approximately 80% of Sri Lankan Chinese live in Colombo and are mainly involved in the dental trade, textile retail, hotel and restaurant industries. In the past, some younger generations of Sri Lankan Chinese left the country due to political instability. Additionally, a fair amount of Sri Lankan Chinese have at times migrated to other countries such as the United Kingdom, the United States and Australia.

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.

Malaysian Chinese or Chinese Malaysians are Malaysian citizens of Chinese ethnicity. They form the second-largest ethnic group in Malaysia, after the Malay majority, and as of 2020, constituted 23.2% of the country's citizens. In addition, Malaysian Chinese make up the second-largest community of overseas Chinese globally, after Thai Chinese. Within Malaysia, the ethnic Chinese community maintains a significant and substantial presence in the country's economy.

Most Malaysian Chinese are descendants of Southern Chinese immigrants who arrived in Malaysia between the early 19th and the mid-20th centuries before the country attained independence from British colonial rule. The majority originate from the provinces of Fujian and Lingnan (including the three modern provinces of Guangdong, Hainan and Guangxi). They belong to diverse linguistic subgroups speaking Chinese such as the Hokkien and Fuzhou from Fujian, the Teochew, Cantonese, Hakka from Guangdong, the Hainanese from Hainan and Kwongsai from Guangxi. Most Malaysian Chinese have maintained their Han Chinese heritage, identity, culture and language.

Philippine Hokkien is a dialect of the Hokkien language of the Southern Min branch of Min Chinese descended directly from Old Chinese of the Sinitic family, primarily spoken vernacularly by Chinese Filipinos in the Philippines, where it serves as the local Chinese lingua franca within the overseas Chinese community in the Philippines and acts as the heritage language of a majority of Chinese Filipinos. Despite currently acting mostly as an oral language, Hokkien as spoken in the Philippines did indeed historically have a written language and is actually one of the earliest sources for written Hokkien using both Chinese characters (traditionally via Classical Chinese (漢文; Hàn-bûn) worded from and read in Hokkien) as early as around 1587 or 1593 through the Doctrina Christiana en letra y lengua china and using the Latin script as early as the 1590s in the Boxer Codex and was actually the earliest to systematically romanize the Hokkien language throughout the 1600s in the Hokkien-Spanish works of the Spanish friars especially by the Dominican Order, such as in the Dictionario Hispánico-Sinicum (1626-1642) and the Arte de la Lengua Chiõ Chiu (1620) among others. The use of Hokkien in the Philippines was historically influenced by Philippine Spanish, Filipino (Tagalog) and Philippine English. As a lingua franca of the overseas Chinese community in the Philippines, the minority of Chinese Filipinos of Cantonese and Taishanese descent also uses Philippine Hokkien for business purposes due to its status as "the Chinoy business language" [sic]. It is also used as a liturgical language as one of the languages that Protestant Chinese Filipino churches typically minister in with their church service, which they sometimes also minister to students in Chinese Filipino schools that they also usually operate. It is also a liturgical language primarily used by Chinese Buddhist, Taoist, and Matsu veneration temples in the Philippines, especially in their sutra chanting services and temple sermons by monastics.

Ethnic Chinese in Brunei are individuals of full or partial Chinese descent, primarily Han Chinese, who are either citizens or residents of the country. As of 2015, they make up 10.1% of Brunei's population, making them the second largest ethnic group. Brunei is home to one of the smaller overseas Chinese communities, with many Chinese people in the country being stateless.

Ethnic Chinese in Brunei were encouraged to settle due to their commercial and business acumen, with the largest subgroup being the Hokkien, many of whom originated from Kinmen and Xiamen in China, followed by smaller groups of Hakka and Cantonese. Despite their relatively small numbers, the Hokkien have a significant presence in Brunei's private and business sectors, contributing their entrepreneurial expertise and often partnering with Malaysian Chinese enterprises in joint ventures. The non-state commercial sector in Brunei has been largely dominated by ethnic Chinese who immigrated during the British colonial era.
