During the height of the Sanguine War, Chang Gang led by Mr. Kebun attempted to aid the Sanguine Freedom Fighters in any way they could, whether by ambushing and attacking the aircraft carriers holding the artillery and sending people to ambush those on the aircraft carrier, or transporting essential supplies, necessary equipment and in some instances extra fighters through the treacherous seas from Los Santos to Sanguine Island.
However, despite all efforts to aid the fighters, it was all for naught as the forces of the Los Santos Government and allies crushed the Sanguine Island fighters. The aftermath of the war proved to be very bad news for members of Chang Gang as they now became the primary targets and focus of the UPD and the LS Government when the details of their involvement came to light. With nothing else left for CG to handle in Los Santos, the decision was made for CG to flee Los Santos toward Guatemala, where they would trek through rough and dangerous terrain to find refuge at the cocoa plantations of Bobby Brown, where his world-famous cocoa butter is produced and shipped from. While the majority of the members of Chang Gang fled Los Santos, only Pigeon stayed behind to maintain continuity within the Los Santos leadership.
CG spent the next few years helping with the operations of Bobby’s cocoa butter manufacturing and also defending the plantations from rebels and enemy farmers attempting to ruin operations.
However, nearly 5 years after they arrived in Guatemala, things turned sour for the operations as batches of Bobby Brown's cocoa butter began to produce some horrific side effects, such as deformities in users of the cocoa butter. The worldwide outrage over the issues with the cocoa butter, which included drooping skin and loss of feeling in muscles, forced the Guatemalan authorities to act and set loose multiple forces to shut down the entire operation. Realizing that they were in danger, they set out to try and attempt to save the farm, getting into day-long gunfights with the Guatemalan authorities. The call was made to flee Guatemala and return to Los Santos, however, upon some members’ return, it was discovered that the City of Los Santos fell into disrepair, and with it, Chang Gang lost everything, from their assets to their business to their homes, everything was seized and the city in ruin.
Mr. Kebun set out to lead and rebuild Chang Gang, reclaiming its top status once again in the city of Los Santos.
