: I will talk about explicit studies on the birational geometry of Q-Fano threefold weighted complete intersections of codimension two. I will explain which Q-Fano WCI is birationally rigid or not. For birationally non-rigid Q-Fano WCIs, we can construct explicit links to another Mori fiber spaces. I will show that some of them are birationally birigid, that is, there are exactly two Q-Fano varieties in their birational classes.
