摘要：
We demonstrate that contributions of hadronic intermediate states can give a possible solution to puzzles in non-leptonic weak decays of K and charm mesons, in particular, exotic four-quark mesons play an essential role in charm meson decays and also in the small violation of the so-called \Delta I\ = 1/2 rule in K --> --> pi pi decays. A brief comment on B-meson decays is also provided.
