Chin'itsu (Perfect flush) Rather than chin'itsu, that hand actually qualifies for yakumans ryuuisou (all green tiles) and suuankou-tanki (four concealed triples, waiting for the pair). Assuming a ruleset where yakumans stack, ryuuisou counts single regardless whether hatsu is involved, and suuankou-tanki counts double, that's been a triple yakuman.
