Analysis

Written by an AI model from the sources above. It is a reading of them, not a source in its own right: every figure in it points back to a numbered source, and where the two disagree, the source is right.

Assessment

Confidence
catalogued listed in a variant catalogue with tile counts and hand sizes, but no rules text verified
Evidence
corroborated two or more independent sources agree on the facts that define this variant

  • [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.

In the tree

Descends from Shanghai / Hong Kong new style, as the source chart draws it.

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.
