All four wind pungs.
Pungs or kongs of all four winds: East, South, West and North, plus any pair. It is a limit hand.
Twelve of the sixteen wind tiles must reach one hand. The pair is free, which is the only concession the pattern makes.
It is a hand you fall into from Small Winds rather than one you plan. If three wind pungs arrive, the fourth is worth waiting for only while the tiles are still live.
Count how many of that wind you have seen. After two are gone, it will not come.
Breaking Small Winds to reach it. Small Winds is already six faan plus the wind rows. Giving up a made hand for a fourth specific triplet is how a large hand becomes no hand at all.
Seat Wind and Round Wind both score inside it, since your own wind and the round wind are necessarily present. It also implies All Pungs. As a limit hand the total is capped regardless, so those rows are confirmation rather than addition.
Does the pair have to be an honour?
No. The pair can be anything. Only the four wind sets are required.
Do I score Seat Wind as well?
Yes, though the hand is already at the limit, so it makes no practical difference.
Is it harder than Great Dragons?
Yes. Four wind sets against three dragon sets, which is why it is a limit hand and Great Dragons is eight faan.
