Los Santos Triads

"Hey I got off clean - you dudes ain't goin' have no more Triads coming after you."

- Franklin Clinton to Trevor Phillips after killing Triad leader Wei Cheng

The Los Santos Triads, formerly known as the Wei Cheng Triad, are a large Chinese crime syndicate in Grand Theft Auto V and Grand Theft Auto Online, appearing as the secondary group of antagonists, alongside the Ballas and The Lost MC.

The Triads are led by Wei Cheng, the father of Tao Cheng, during the events of GTA V in 2013, and by an unnamed Triad boss in 2020, during the events of Gerald's Last Play in GTA Online.

Events of Grand Theft Auto Online
They can appear in at least three Gang Attacks:
 * Dignity Village north of Mount Chiliad;
 * Rancho Projects in Rancho;
 * At the farm north of La Fuente Blanca (although sometimes these spawn the Armenians or the Professionals instead).

They are also one of the few gangs that can be encountered during the resupply missions of the Bikers businesses.

Events of Grand Theft Auto V
Tao Cheng, the son of triad boss Wei Cheng, and his translator meet with drug dealer Trevor Phillips about a business partnership, as the Triads seek to expand into Blaine County. However, they end up choosing to do business with the O'Neil Brothers instead, due to Trevor's violent and reckless behavior, along with an attack on his meth lab by the Varrios Los Aztecas during a tour with Tao and his translator. Trevor learns about the partnership when he assaults Tao and forces the translator to reveal their partners, after which he kills most of the O'Neil brothers and destroys their farm as retribution for stealing his contract.

In an act of vengeance for assaulting his son and taking out their business partners in Blaine County, Wei Cheng sent some of his men to search for Trevor, briefly scouting him while he and his friend Michael De Santa lived in Trevor's Trailer during their exile from Los Santos by the Madrazo Cartel, incorrectly believing that they were gay lovers. When Trevor and Michael have a falling out and fly up to Ludendorff, North Yankton, the Triads follow them and interrupt them during a stand off. Trevor manages to escape, but Michael is captured. While flying back, Trevor receives a call from Wei, who informs him of Michael's capture and that he will die if Trevor does not meet with him. Trevor, mad at Michael over their falling out, declines to help him.

Michael is held at the Raven Slaughterhouse in Cypress Flats for a short while, until Wei realizes that Trevor isn't coming and orders Michael to be killed in one of the meat grinders. Michael and Trevor's friend, Franklin Clinton, with the help of their associate, Lester Crest, fights his way through the slaughterhouse, killing dozens of Triad members, including the Triad underboss, and rescues Michael.

Eventually, Franklin, Michael, and Trevor team up one last time to take down their enemies once and for all. Lester tracks Tao's credit card to the Pacific Bluffs Country Club, which Franklin arrives at, killing Wei.

Despite their leaders' death, they still can be found at Little Seoul at the end of the game

Events of Grand Theft Auto Online
In the After Hours update, the Triads appear in Destroy all rival supply trucks Nightclub Management missions as enemies working for the rival Nightclub, Bahama Mamas.

In The Diamond Casino & Resort update, Tao Cheng's uncle, who is became head of Cheng family businesses after Wei's death, bought the casino and placed Tao in charge. While it is mentioned that he is the boss of the Cheng Family and Cheng Family Holdings, Wei Cheng's Triad appears to be lead by an unnamed boss, though he does not make any appearances. It is possible that the Triad boss, along with the Los Santos Triads themselves, work directly under the Cheng Family. A rival crime family, the Duggans cause enough trouble for the Chengs that they are forced to sell the casino to them, after which, Tao Cheng and his translator leave Los Santos.

In The Diamond Casino Heist update, Tao's sister, Georgina Cheng, recruits Lester Crest and the GTA Online Protagonist to repeatably rob the casino to get revenge on the Duggans.

Gerald contacts the informs the GTA Online Protagonist that the unnamed Triad boss is a long time rival of his, and that he wants to get back at him. The player, sent by Gerald to the Raven Slaughterhouse, where the boss is running a drug operation, kills him.

In The Contract update, the protagonist, now working for F. Clinton and Partner, is hired to briefly help protect casino equipment under attack by Triad members. The player protects the equipment from numerous waves of attackers until help arrives. The player is also hired by an unnamed importer to take out several Triad lieutenants who had been undercutting him. The player fights through Triad members and kills the lieutenants.

Trivia

 * Their favorite radio station is Soulwax FM.
 * They may be influenced by the Black Dragons Triads that are based in Los Angeles.
 * A Weazel News broadcast in GTA V states that Globalpol have shared intel that a number of Chinese criminal organisations have begun operating in the U.S. with a view of infiltrating the North American drug market, despite them already being heavily involved in it during GTA IV (five years earlier) and most notably in GTA Chinatown Wars, where the protagonist is a member of the Triads himself (four years earlier). It is unclear if this is supposed to be humorous or is simply an oversight on Rockstar's part.
 * Despite becoming their main enemy later in the game, Trevor never fights the Triads in any of GTA V's missions. Also, if Trevor sets foot on the Triads' territory, they will not attack him on sight, unlike The Lost MC.
 * As of the After Hours update, the Triad presence has been increased almost all around the map of Los Santos, making situations more dangerous, especially if they are armed with weapons. Additionally, it can also interrupt other freemode missions, increasing their difficulty.
 * The Triads' logo bears an amazing resemblance to the logo of the  video game franchise, except with the dragon flipped the other way and colored red instead of black.
