In the past decade, exotic hadrons with charm and bottom flavors have been extensively studied both in experiments and in theories. In this review, we provide topical discussions by selecting X,Y,Z particles, to which Belle has made important contributions. These are X(3872), Y(4260), Z_c(4430)^+, Z_c(3900)^+, Z_b(10610)^+ and Z_b(10650)^+. Based on the current experimental observations, we discuss those states with emphasis on hadronic molecule whose dynamics is governed by chiral symmetry and
