Triad (organised crime)

• 1. Introduction

  ›

  A triad is a Chinese transnational crime syndicate, and its recruits have traditionally been sworn in at an altar dedicated to the warrior god Guan Yu. Incense burns there, and an animal is sacrificed, usually a chicken, pig, or goat. The candidate drinks wine mixed with blood, either the animal's or his own. He then walks beneath an arch of swords while reciting the group's oaths. Afterwards the paper carrying those oaths is burnt on the altar, sealing his duty to the gods. Three fingers of his left hand are raised to bind the promise, and he must keep 36 oaths in all.

  Today, police and investigators on several continents accuse groups of this kind of extortion, drug trafficking, and money laundering. Yet the secret societies behind the name were not obviously criminal at first. Why did brotherhoods sworn against a ruling dynasty turn to protection rackets? Why is the very word "triad" disputed? How does a gang with ranks numbered 489 and 49 hold together, and why do governments keep appearing in its story?

  ›

  The English word triad, according to the Oxford English Dictionary, translates the Chinese San He Hui, written 三合會. The name refers to a union of heaven, earth, and humanity. A rival theory says British officials in colonial Hong Kong coined it after noticing triangular imagery. That story is highly improbable, because William Milne was already using the word for secret societies in Southern China in 1826, well before the colony existed.

  Using "triad" for every Chinese criminal group is imprecise. True triads are traditional organised-crime groups from Hong Kong, Macau, and Taiwan. Groups from mainland China are better called mainland Chinese criminal groups or black societies. Mainland gangs come in two types: loose "dark forces" and more mature black societies. What sets the second type apart is how far it controls local markets and how much police protection it can obtain.

  The Tiandihui, or Heaven and Earth Society, is the best-known ancestor. It was also called Hongmen, the Vast Family, and began as a fraternal organisation and secretive folk religious sect. Its own ancestor was the Ming loyalist White Lotus Sect, and some societies were influenced by white lotus groups as far back as the 14th century. As the Tiandihui spread through counties and provinces, it split into many branches, among them the Sanhehui.

  These branches shared a political purpose. They wanted to overthrow the Qing dynasty, whose Manchu rulers were seen by the Han majority as foreign and tyrannical. By the turn of the 19th century the Qing looked corrupt and unable to reform, and the societies marched under the slogan "Oppose the Qing and Restore the Ming dynasty." Some historians have speculated that triads grew out of, or took after, the White Lotus, the Taiping Rebellion, and the Boxer Rebellion.

  Overseas, the societies served a quieter function. They helped immigrants from China find work and build local connections in their new homes. Some Hongmen branches abroad became known as Chinese Freemasons, and the modern form of that tradition is purely secular. During the Taiping Rebellion, many members aided the Taiping Heavenly Kingdom against the Qing, some willingly and some under compulsion.

  Colonial governments saw the matter differently. Hong Kong banned triads in 1845, and it is argued that they monopolised the labour market from 1857. In the 1890s Singapore banned secret societies, along with the opium trade and prostitution that fed their power. Immigrants were steered toward local kongsi instead. By the end of the century, at least one-third of Hong Kong Chinese were estimated to belong to a triad.

• 3. Republic and Exile

  ›

  In 1927, members of the Green Gang, a splinter of the Hung Society, took part in the Shanghai massacre of Chinese Communist Party members. The Nationalist Kuomintang had enlisted triads in the Republican era to attack and assassinate political enemies. The most prominent triad leader of the 1930s was arguably Du Yuesheng.

  The scholar Chu Yiu-kong argues that modern triads did not begin in Hong Kong. In his account they grew out of mainland China, shaped by an influx of refugees. Their network carried opium, but it also carried ordinary trade, helped with labour disputes, and supported the republican movement. In this telling, the triad was above all a mutual-assistance group for migrant workers.

  After World War II, gangsters exploited the uncertainty to rebuild their societies. The "new villages" around Kuala Lumpur and the Bukit Ho Swee district of Singapore became notorious for gang violence. Elsewhere in Southeast Asia, triads in the crown colonies of Malaysia and Singapore extorted protection money and ran illegal lending. Some operated opium dens and brothels. Government campaigns have since pushed the societies largely out of public view, especially in Malaysia.

  Vietnam shows how differently governments could respond. Under French rule, protection-racket gangs controlled many businesses and wealthy residents in Saigon's Chinatown and in Haiphong. After independence in 1945, Ho Chi Minh's government purged criminal groups, and the French in turn cooperated with criminals against the Viet Minh. In 1955 President Ngo Dinh Diem ordered gangs in the Saigon region and Mekong Delta towns disarmed, yet he let some crime continue to fund his fight against the Viet Minh. In the north triads were eliminated during the Vietnam War, while in the south corruption protected them and let them control American aid. By the 1970s and 1980s Vietnamese police had eliminated illegal Sino-Vietnamese activity, and most triads fled to Taiwan, Hong Kong, or other Southeast Asian countries.

  The largest flight came after the People's Republic was proclaimed in 1949. Mao Zedong ordered campaigns that suppressed secret societies, and in 1978 Deng Xiaoping launched his "Strike Hard" crackdown on organised crime. Most triads and remaining Green Gang members moved to Hong Kong, Taiwan, Southeast Asia, and overseas countries, especially the United States. There they competed with the Tong, a different kind of Chinese organisation. Tongs were social clubs formed in the second half of the 19th century by marginalised Chinese-American immigrants seeking mutual support and protection from nativists. Modelled on triads but without clear political motives, they too drifted into extortion, gambling, and trafficking. Exiled triads, meanwhile, turned gradually to the drug trade and extortion for income. Their most important refuge was a British colony.

• 4. Hong Kong's Big Four

  ›

  The University of Hong Kong says most triad societies in the territory were established between 1914 and 1939, and there were once more than 300 of them. In the 1950s an estimated 300,000 triad members lived in Hong Kong. Over the following decades the number of groups consolidated to about 50, of which 14 are under police surveillance.

  Four main groups, known in Chinese as the Big Four, carved the territory up. They were the Chiu Chow Group, which includes Sun Yee On; the 14K; the Wo Group, which includes Wo Shing Wo; and the Sze Tai. Each divided land by ethnic group and geography, and each ran its own headquarters, sub-societies, and public image.

  In the 1960s and 1970s the notable leaders included Ng Sik-ho and Ma Sik-chun in Hong Kong and Stephen Tse in Boston. In the early 1980s a surprising negotiator appeared. Wong Man-fong, a Chinese Communist Party official at the Xinhua News Agency, talked with Hong Kong triads on Beijing's behalf. His aim was to keep the peace after the handover of Hong Kong.

  The 1980s and 1990s then brought down several prominent figures. The arms smuggler Cheung Tze-keung, the triad leader Wan Kuok-koi, and Peter Chong, convicted of racketeering and extortion, all ended up in prison. Entertainment figures also drew suspicion, among them the Taiwanese director Jimmy Wang Yu and the Hong Kong film producer Charles Heung, both suspected of ties to organised crime.

  Hong Kong answered with law. The Societies Ordinance of 1949 outlawed triads and allows a fine of up to HK$1 million and up to 15 years in prison for anyone convicted of being, or claiming to be, an officeholder. In 1974 the Independent Commission Against Corruption was set up, and it went after police corruption linked to triads. A 1994 ordinance made mere membership an offence, with fines from HK$100,000 to HK$250,000 and three to seven years in prison. It also gave police special investigative powers and let courts confiscate the proceeds of crime. Police still raid triad-controlled entertainment venues and use undercover work. Inside the societies, rank was once recorded in numbers.

• 5. Ranks and Numbers

  ›

  The number 489 marks the top of a traditional triad. It belongs to the Mountain Master, also called the Dragon Master Head, and the numbers come from Chinese numerology based on the I Ching. The Deputy Mountain Master is 438. The Red Pole, a military commander who oversees defensive and offensive operations, is 426. An ordinary soldier, the rank-and-file member, is simply 49.

  The specialist roles carry numbers too. The White Paper Fan, 415, gives financial and business advice. The Straw Sandal, 432, acts as a liaison between units. The Incense Master oversees inductions, and a Vanguard assists him. Law enforcement and intelligence sources say the Vanguard may actually hold the final word. Blue Lanterns are uninitiated members, comparable to Mafia associates, and have no number.

  One number carried a double meaning. An undercover law-enforcement agent, or a spy from another triad, is 25. In Hong Kong slang the same number also means an informant.

  How much of this survives is doubtful. De Leon Petta Gomes da Costa interviewed triad members and authorities in Hong Kong. His conclusion is that most of the current structure is vague and low in hierarchy, and that the traditional ranks and positions no longer exist.

  The nicknames of leaders show the culture that remains. Kwok Wing-hung was known as "Shanghai Boy" and was Wo Shing Wo's most notorious dragonhead, while Cheung Chung-wing, "Inch Brother", also led Wo Shing Wo. Raymond Chow, called "Shrimp Boy", led the American branch of Wo Hop To. Wan Kuok-koi, known as "Broken Tooth", led the Macau branch of the 14K. Michael Chan, a Hong Kong actor and martial artist, was second-in-command of the 14K's Tsim Sha Tsui branch.

  A few names break the pattern. John Willis, a high-ranking member of the American group Ping On, is described as the only white person to hold a senior triad rank. Xie Caiping, nicknamed the "Godmother of the underworld", was the most powerful criminal in Chongqing and was convicted in the Chongqing gang trials. Chen Chi-li once led Bamboo Union, Taiwan's largest triad. What these groups sell is the next question.

  ›

  Opium bans in the 19th century gave Chinese gangs a lasting place in the global drug trade. In the 1960s and 1970s many triads moved from opium to heroin, made from poppies grown in the Golden Triangle and refined in China. Shipments went on to North America and Europe, and the 14K and the Big Circle Gang are named as the most important triads in the international heroin trade.

  Today the chemical routes run in the other direction. Triads smuggle chemicals from Chinese factories to North America to make fentanyl and methamphetamine, and to Europe to make MDMA. They are also increasingly involved in unlicensed cannabis cultivation in the United States. In the United States they traffic large quantities of ketamine, and triad figures are responsible for large-scale drug trafficking into Australia.

  Money laundering may now matter even more. Triads are reported to be the principal launderers for drug cartels in Mexico, Italy, and elsewhere, and to move money for the Chinese Communist Party elite. The United States House Select Committee on Strategic Competition between the United States and the Chinese Communist Party says the opioid epidemic helped them become "the world's premier money launderers." In the 21st century, Chinese crime groups have also laundered cryptocurrency stolen by North Korean hackers. Triads are active in various cryptocurrency scams, including pig butchering schemes.

  Counterfeiting is the oldest sideline. Triads have faked goods since the 1880s, and in the 1960s and 1970s they forged currency, often the Hong Kong 50-cent piece. They also counterfeited expensive books for the black market. Later came watches, film VCDs and DVDs, and designer clothing and handbags.

  Since the 1970s, triad control of territory has weakened, and some groups moved income into legitimate businesses. A 2007 estimate by Shanty and Mishra puts annual profit from narcotics at 200 billion dollars. It puts annual revenue from human trafficking into Europe and the United States at 3.5 billion dollars. Those revenues explain why the trade now follows Chinese communities abroad.

  On the 18th of January 2018, Italian police arrested 33 people tied to a Chinese triad in Operation China Truck, an investigation that had begun in 2011. The group was active in Tuscany, Veneto, Rome, and Milan, and also in France, Spain, and the German city of Neuss. The indictment alleged extortion, usury, illegal gambling, prostitution, and drug trafficking. Prosecutors said it had infiltrated road transport by threatening Chinese companies that wished to ship goods into Europe. Police seized vehicles, businesses, properties, and bank accounts.

  The expert Antonio De Bonis describes a close relationship between the triads and the Camorra, with the port of Naples the main landing point for Chinese-managed trade. Together they are linked to human trafficking, illegal immigration, synthetic drug trafficking, and laundering through property purchases. In 2017, investigators found a scheme run jointly by both groups to ship industrial waste from Prato to Hong Kong. Before its discovery it had earned millions of US dollars for both organisations.

  Violence has followed. In April 2025, Zhang Dayong, known as Asheng, was shot dead in Rome with one shot to the head and three to the chest. He was the right-hand man of Zhang Naizhong, the alleged head of the Chinese mafia in Europe. Officially Asheng ran a store in the Esquilino neighbourhood, but investigators say he ran loan sharking and underground gambling for the organisation. He had attended the lavish 2013 wedding of Zhang Naizhong's son. Intercepted conversations suggest his drinking, his disrespect toward superiors, and his assaults on women at a brothel had cost him favour. His killing is believed to be linked to the "hanger war" of Prato, which has spread to Rome. In August 2025 Italian authorities arrested 13 people connected to Chinese organised crime.

  A case in Turin, reported in February 2026, shows the quieter side. Liu Jianwei, known as "Dan", was active in clandestine mahjong dens and lent cash to Chinese players at rates reportedly up to 20 percent per month. In March 2025 a cook named Hu Libin, who owed gambling debts he could not repay, killed him. Authorities call it a settling of accounts inside a "rooted and structured" system of usury. Handwritten lists of debtors and amounts owed were found.

  In Australia, police sources say the main importer of illicit drugs in recent decades has been "The Company", a conglomerate run by triad bosses that focuses on methamphetamine and cocaine. It has laundered money through junkets for high-stakes gamblers who visit Crown Casinos in Australia and Macau. In South Africa, authorities name four major Chinese gangs tied to the triads: Wo Shing Wo, San Yee On, 14K-Hau, and 14K-Ngai. On the 22nd of November 2022, rival factions fought a shoot-out on a crowded Cape Town street, and several bystanders were injured.

  Reporters in the 2000s noted that Sun Yee On appeared to send teams from China to São Paulo as enforcers against anyone who failed to pay protection money. In 2003 a senior official at Japan's National Police Agency in Tokyo said clashes between the yakuza and Chinese gangs were increasing. In Canada, a 2011 estimate said triad-linked gangs controlled 90 percent of the heroin trade in Vancouver. Questions about who protects such networks lead back to governments.

• 8. Party and Patriots

  ›

  The Washington Post has described the Chinese government's "selective use or tolerance of criminal groups for geopolitical purposes." It adds that mixing illicit activity and patriotism "has become a hallmark of some Chinese organizations with overseas interests." The link traces back to the triads' history of "patriotic" work for political movements, and reports tie them to the Chinese Communist Party, often through its united front groups.

  According to those reports, triad members have acted as agents of the party-state. They have suppressed dissent, quelled protests, and intimidated critics at home and abroad, particularly in Hong Kong, Taiwan, and countries with large Chinese diasporas. Martin Purbrick says the Party "recognised the benefit of triads as part of their United Front activities to neutralise opposition." Organised crime also gives the Party plausible deniability for political warfare.

  The 2019 Yuen Long attack on pro-democracy protesters in Hong Kong is cited as an example. Hong Kong police were later accused of collusion with triad syndicates, because officers were notably absent at the scene despite a heavy presence at protests in earlier weeks. Foreign Policy reported alleged triad involvement in repressing the Hong Kong protests in its August 2019 edition. In Taiwan, the triad figure Chang An-lo founded the pro-Beijing Chinese Unification Promotion Party.

  Corruption inside China makes the arrangement possible. Triad activity rose on the mainland in the 1980s amid economic and political change, rapid urbanisation, and growing demand for illicit goods. Reports describe corrupt links among gang leaders, village heads, party secretaries, and local public security officers who oppressed residents. Later crackdowns, such as one in Zhanjiang City, dismantled gangs that controlled sand-mining, seafood, and basket industries. Those campaigns also raised concern about minors drawn into drug distribution and smuggling.

  Foreign officials have raised similar alarms. In June 2022 Reece Kershaw, commissioner of the Australian Federal Police, told the Five Eyes Law Enforcement Group that "state actors and citizens from some nations are using our countries at the expense of our sovereignty and economies." In 2020 the United States Treasury sanctioned Wan Kuok-koi under the Magnitsky Act for corruption, embezzlement, and misappropriation of state assets.

  Investigative reporters have followed the thread across the Pacific. A 2022 report by the Organized Crime and Corruption Reporting Project linked triad figures connected to Wan Kuok-koi with united front influence operations in Palau. In 2023 a ProPublica investigation found that leaders of certain overseas Chinese police service stations had ties to organised crime. In 2024 the Organized Crime and Corruption Reporting Project and The Age reported similar connections in the Pacific, particularly in Fiji.
