Chinroutou 「清老頭」 is a yakuman, where every tile is a terminal, or 1's or 9's. The term for terminals is routouhai 「老頭牌」.
Tile pattern
Agari: or
Routouhai
Routouhai 「老頭牌」 are the tiles numbered 1 or 9, among the numbered suits. In English, they are denoted as terminals, because they are at the end of the 1 to 9 number scale. Also, the numbered suits do not loop, when it comes to forming tile groups.
Formulation
For this yakuman, there are only six types of terminals available: two from each of the numbered suit (1 and 9). Given the basic hand pattern of four melds and a pair, five out of the six types of terminals are needed to build this hand. Since there are only six tile types available for this hand, it is impossible to form a chiitoitsu variation.
