Wei Jiang

Wei Jiang is the main antagonist of the first season for the Sanchez family. He is the leader of the Hong Kong Triads.

Early Life
Wei Jiang is a Chinese-born mobster hailing from Yangshan in 1972. He became the head of the Hong Kong Triads gang, which primarily deals in gunrunning and trafficking drugs, with his spoiled only son Tao. By 2018, his operation had grown heavily, and he seek to expand his business into Los Angeles.

Expanding Business
In order to fulfill his goal of expanding his business into LA County, Jiang decided to give Tao another chance of proving himself by sending him and his translator to make contact with Nacho Sanchez, one of the area's most prominent drug dealers and a member of the notorious Sanchez crime family. However, an attack on Nacho by a group of Archangels bikers, who were angered and vengeful because of Nacho's murder of their president dissuaded Tao and Ken Nao from working with him, instead deciding to collaborate with the rival Baker Brothers. This change of plans prompted Nacho to assault Tao and interrogated him about his new collaborators. After realizing the Bakers had stolen his contract, Nacho, in a fit of rage, wiped out the Bakers and destroyed their farm then continued to wage war against other rivals across the county to prevent the Jiangs from dealing with them too.

Loss of his Son
Meanwhile, Wei had purchased a penthouse at a high-end casino in the city where he was conducting his business from. After Nacho had killed all of his rivals, Tao ran away from the county to his father's penthouse where he informed him of his miserable failure. Initially Wei appeared calm and he even offered his son a drink to his surprise, only for him to gut-punch him to spit it back out and then forced him to clean it up. Wei angrily berates Tao, calling him useless and showing his absolute hatred towards him before fixing a drink for himself. Tao though stopped cowering and he decided to stand up, bravely telling his father that he would rectify his errors through retribution against Nacho. Wei only swiftly dismissed Tao and warned him not to damage their reputation further, causing him to storm off enraged with a gang accompanying him to exact his revenge on Nacho.

While Tao was fleeing from the strip club, he tried to call Wei, who was in the middle of smoking marijuana in his office, though he ignored his son's desperate call for help cruelly and left him for dead. Wei was later called again but this time by Sebastian Bolsa, Nacho's lieutenant, who revealed to Wei that they were holding Tao hostage. Seb tried to ransom with Wei for his son's safety, demanding a large sum of $350,000 in exchange that they release Tao. Wei though turned down the ransom coldly and explained that he despised his son for disgracing the family name and being more hurtful to his business than helpful. Wei ultimately abandoned his son without a shed of care for him at all, leading to Nacho into torturing and murdering Tao out of revenge. However, unbeknownst to the Sanchez crew, Wei had the phone they used to call traced and sent a handful of his thugs to kill them led by his underboss, Tsai Lin, in retribution for harming his reputation and business expansion plans. However, the attack on the crew failed and sparked a gang war between the Sanchezes and the Triads.

War on Nacho Sanchez
Christian Sanchez, who was the Sanchez family boss and found out what happened recently, he tried to reason with Wei via a phone call but Wei silently refused. Wei placed a $1 million contract for Nacho's death and personally offered the contract to Australian hitman Oscar Jackson, considered one of the best assassins in the business, who accepted. However, Jackson managed to negotiate with Wei to make the bounty $2 million if he captured Nacho alive so he could "have fun" with him personally before taking his life. Wei agreed to these terms happily.

Upon learning that the laundry place that was laundering Wei's money and hiding his incriminating documents on corrupt city officials and cops was raided by Nacho's crew, Wei ordered Tsai to murder the business owner as punishment for failing to protect his money. A strategic ambush was set up by Nacho's crew and their secret informant, Wei's translator Ken Nao, in an attempt to take out Wei though the attack failed and Wei managed to escape. Wei retreated from the firefight back to his safehouse, though he was surprised when it was revealed by Tsai that she managed to capture Seb. Wei came to realize that there was a mole within his organization who was supplying Nacho with information, discussing these matters with Tsai and Nao. Wei gave Tsai orders before departing to make a phone call. Wei then interrogated Seb into revealing who his informant was, though Seb refused to answer Wei's questions and was beaten and tortured as a result. Wei then had Tsai bring in the "negotiation hostages" which were revealed to be Seb's sister and father, whom were threatened by Wei. Seb decided to reveal it was Nao to save his family, who Wei proceeded to have murdered in front of everyone. Wei then killed Seb's father, before turning to Seb to tell him that he hadn't forgot it was him who kidnapped his son and allowed him to be tortured to death. Seb was unable to speak in horror at his father's corpse before Wei left him and took his sister away, telling his men to keep an eye on Seb and reveals he's keeping him alive because he still has some use for him.

Death
After Nacho managed to uncover Seb's location from interrogating two of Wei's minions in brutal fashion, he embarked on a mission to rescue him and set up a plan working with Oscar, who is actually a friend of his family and their frequent hitman. However, Seb managed to free himself from his binds and he set out to save his sister and vengefully murder Wei for killing his father. Using his cunning and skill, Seb murdered a henchman and interrogated another to find out where his sister was; on her way to an airfield to be sold off into slavery. Wei's compound was unexpectedly attacked by Nacho and his crew, who gunned their way through the building in search for Wei and Seb.

Accompanied by Tsai and Seb's sister, Wei was in his private car where he was being driven to the airfield. Wei took pleasure in telling Seb's sister about his criminal activities and horrifically described what "he" did to his only son, implying that he slightly cared for his son and had regretted causing his death. Wei also informed her that he was going to make money out of her from the human trafficking market, then he will ensure that Seb will suffer from a slow, painful death after using him to eliminate Nacho and take down his operation. When the driver suddenly stopped in a remote location, Wei was confused before the driver suddenly shot Tsai to death. The driver ordered both Wei and Seb's sister out of the car at gunpoint, revealed to be Seb himself much to Wei's surprise. Seb instructed his sister to leave with the car and dump it somewhere discrete. She pleads with him, though Seb shouts at her to go and was distracted for Wei to wrestle Seb for the gun.

Wei and Seb fight over the gun, resulting in Wei winning and he prepares to execute Seb but his head was suddenly blown off by a sawn-off shotgun. It was revealed Wei's killer was Nacho, who followed them out into the desert to save Seb because he believed Wei was still holding Seb prisoner in the car.
