(mahjong) little three dragons: a 役 (yaku, “hand”) with triplets or quads of two of the 三元牌 (sangenpai, “dragon tiles”), plus a pair of the third; worth 2 翻 (han, “doubles”). Because 2 翻 is added from the 役牌 (yakuhai, “meld of seat/prevailing wind or dragon”) of the two dragons, the total is actually 4 翻.

(mahjong) Generic name of the three dragon tiles: 白 (haku, “white dragon”), 發/𤼵 (hatsu, “green dragon”), and 中 (chun, “red dragon”)
