you probably played in a Singapore or Taiwan server . it happens to me , As i play from south asia and usually connected European server but sometimes switched to those asian server. as i studied chinese language for 3 years , so i could understand them Almost. and yeah , many are cheaters from that region but not all , some are play fair.
well im good in listening and speaking chinese but not THAT good in reading or writing , i checked some of these CHINESE websites using their famous search engine ( baidu) . where i could find CHEATS for Apex legend. couldnt find much , but i found one website that they selling cheats for many online games (mostly chinese games) . they have very powerfull apex legends cheats like , full accuracy , unlimited ammo , instant ultimate , SPAWN weapons n loot , speed hack , jump hack , wall hack . And most important BYPASS HWID ban . My lord , whole full package
So you wonder why soo many asian cheaters.
