Caveat from the source chart
These eleven nodes stand in for a hundred-plus real variants, most undocumented in English. The group began on a Chinese Classical frame and only later adopted HKOS's simplified scoring, so its placement under Hong Kong old style is a simplification.

- [1] states there are over 100 variants of Mainland Mahjong today, but that as late as 1990 regional variants shared many rules; in the 1990s they began deviating, Sichuan/Chengdu added Bloody rules, some dropped Joys, some removed honours, some built on Old Style and some on an additive New Style. Chinese Classical is said to have been allegedly invented in Ningbo in the 1900s, with later pattern additions referred to as Shanghai New Style
Reading it
The wiki independently confirms both of the chart's caveats about this group: over 100 variants today, and a 1990s divergence in which some built on Old Style and some on an additive New Style. It also dates the Sichuan/Chengdu Bloody rules to the 1990s, matching the chart's separate node.
