Ryanpeikou (二盃口) is a standard yaku, consisting of two "iipeikou". The prefix "ryan" is a Japanese counter for mahjong, signifying for "two".
Tile pattern

. However, it'll only count for pinfu and iipeikou.
Compatability
Chii toitsu
This yaku does not combine with chii toitsu. By definition, chii toitsu is formed by the collection of seven pairs. Although, ryanpeikou may be interpreted as a collection of seven pairs also. However, ryanpeikou is actually composed of sequences, rather than as independent pairs. The pattern simply appears as a collection of pairs.
Formation
At the very least, the hand must initially qualify for the yaku, iipeikou. With tenpai, the tile wait involves a tanki, to complete the pair, or the need to complete the other "iipeikou".
With chinitsu
Some forms of ryanpeikou mixed with chinitsu and tanyao may actually form some optional yakuman, named daisharin (pinzu), daichikurin (souzu), and daisuurin (manzu).
