Shousangen requires yakuhai, from the two groups of dragon tiles. As out of the regular four tile groups are dedicated for dragon tiles, this yaku has no room for the likes of ittsu, ryanpeikou, sanshoku, and sanshoku doukou. Each of those four yaku require three tile groups for their specific requirements. Naturally, tanyao and chinitsu are incompatible because of the dragon tiles.
Value
In general, this yaku is noted as 2 han. However, it is impossible for this yaku to score without two instances of yakuhai from the two groups of sangenpai. In combination, this yaku will never produce a hand worth less than 4 han.
