  We study a new $K\rightarrow\pi\pi$ decay channel with gluons in intermediate
state which is normally neglected within the factorization framework. Both
short-distance and long-distance parts of the amplitude are calculated. The
chiral Lagrangian approach is used for obtaining the long-distance
contribution. The nonperturbative contribution gives an additional enhancement
to $K\rightarrow\pi\pi$ decay amplitude with $\Delta I=1/2$. A sizable
violation of factorization in the $p^4$ order of chiral perturbation theory is
found.
