This article is talking about the (arguably less known?) 4-player competitive game [2], and assumes you already know the difference (which some may not).
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.
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".
> He has been playing mahjong since junior high school days, and admitted that though he has rarely lost a game when he was in school, his current level of ability is average. According to him, he has "tournament luck" and has even won mahjong tournaments between mahjong manga artists. He has also participated in professional mahjong matches. He played about two games against Akagi and Kaiji's voice actor Masato Hagiwara, who is known as one of the best mahjong players in the entertainment industry, and made Hagiwara say "I don't think I can beat him."

Count the total counter-clockwise starting from the dealer (East = 1).
東 East 1 · 5 · 9
南 South 2 · 6 · 10
西 West 3 · 7 · 11
北 North 4 · 8 · 12
East -> South -> West -> North - is that not clockwise? What am I missing?
All chinese card games go counter-clockwise. And the compass directions have a standard order, from 1-4: ESWN. Which is why the seat order is not the same as it would be on a compass.
We've been learning for a few years now and still ignore things like prevailing winds and I don't remember what else off the top of my head. Basically we have a document of our own rules and we add to it as we get more advanced. Eventually we'll play with the winds and seasons and the goal is Hong Kong scoring.
Don't even get me started on scoring when you are gambling (although the dynamics of who pays who and how much is interesting)
OP, can you please include Beijing rules?
Did I miss it, or are the "base points" never explained?
I'd add the note that the whole strategy of mahjong really only gets interesting when you play repeated hands (a full game has at least 16 hands, with each player acting as the dealer once per prevailing wind) and when you're gambling (or otherwise tracking points). Most house rules also enforce a minimum fan value for a winning hand, banning the "chicken hand" which wins but scores no points. We play with a 2 fan minimum. If you just play for mahjong (i.e. a a hand that "wins" the round regardless of score), the game is a pretty uninteresting game of luck, and you're not incentivized to gun for the higher scoring hands.
Though I get the sense that, typically the easiest way to learn how to play a game, is to walk through actually playing the game. Listing out a bunch of facts about how the game works is mostly just confusing for a newcomer - the brain doesn't retain that kind of information well.
The example of this I often give is Magic: The Gathering. Very easy to learn how to play just by playing it with someone who knows. Very difficult to learn how to play if you start with a reference guide on how casting and the stack and priority and resolution works.
