Properties of X(3872) are studied by regarding it as a DD^∗ hadronic molecule with J^PC = 2^-+ in the phenomenological Lagrangian approach. We find that our model with about 97.6 existing data nicely, for example, the ratio B(X(3872) → J/ψπ^+π^-π^0)/B(X(3872) → J/ψπ^+π^-). We predict the partial widths of the radiative decays of X(3872) →γ J/ψ, γψ(2S) and the strong decays of X(3872) → J/ψπ^+ π^-, J/ψπ^+π^-π^0 as well as X(3872) →χ_cJπ^0. Our analysis shows that the measurement of the ratio
