In dou dizhu, is
K-K-K-K-A-A-A-A-4-7 assumed to be a standard hand type?
I understand the '飞机带小翼' (i.e. "airplane with small wings", or consecutive triplets with added cards, for example:
K-K-K-A-A-A-4-7 ) hand type to be a valid hand by way of the Pagat rules and by Wikipedia.
Wikipedia also refers to a hand type called '航天飞机带小翼', or "space shuttle with small wings", which consists of consecutive quads with added cards (e.g.
K-K-K-K-A-A-A-A-4-7). I'm not sure where to find an official, standardized set of rules for dou dizhu because I don't speak Chinese, so I'm trying to figure out if the quads thing is a regional variant.
