  In this paper, we study the holography of quasi-topological gravity in
several aspects. We redo the calculation of shear viscosity on the boundary CFT
with a new method which is associated with conserved Noether current and show
that it has only one mode explicitly. Then we study the butterfly effect in AdS
planar black hole and find it has two butterfly velocity modes because of the
quasi-topological term. We obtain new black hole solution through introducing
matter fields. We calculate the thermoelectric DC conductivity with momentum
dissipation in quasi-topological gravity and find its results are the same with
those of Einstein and Gauss-Bonnet gravities. These results show us explicit
similarities and differences between quasi-topological term and actual
topological term in the context of holography.
