Interesting that in this image it portrays the Triads as being almost benevolent, with no mention of the Imperial Service. If the Imperial Service is the enemy of these community-minded fellows, I guess they're villains? @Section9 already said it, but they actually seem to. And it seems to be their main goal, to the detriment of law enforcement or social cohesion. Considering the Yuandun seem to be the Emperor's most favored unit, it seems quite the opposite - which is one of the things that put people off around Uprising time. Yes, that's a general problem with YJ - the faction seems to have been created with the goal of making other factions look good.
