Formulation
For this yakuman, all kazehai (wind tiles) and sangenpai (dragon tiles) can be used. Given the nature of jihai (honor tiles), they different types cannot be mixed into a meld. Therefore, they must be collected in the form of koutsu (triplets). This yakuman is only reasonably achievable, when in possession of at least multiple toitsu (pairs) of the honor tiles.
