In China it turns out there are lots of rule sets. The city I'm currently living in (Changsha) has it's own ruleset for example, with less tiles than these examples.
mahjong rulesets are wild. I play Japanese mahjong, and the difference between online and a mahjong parlor is quite different, making it interesting to see what people optimize for in those different settings
I think mahjong is probably "house rules the game" though. Pretty sure most mahjong hands probably just were a result of some guy being like "hey this hand looks like it should be scored man".
