/ Abstract
We present the selected recent charm results at Belle: (1) the $CP$ asymmetries and branching fractions for the decays of charm mesons, i.e. $D^{0}\toπ^{+}π^{-}η,\,K^{+}K^{-}η$ and $D^{0}\toφη$; $D_{s}^{+}\to K^{+}π^{0},\,K^{+}η$ and $D_{s}^{+}\toπ^{+}π^{0},\,π^{+}η$. (2) the branching fractions for the decays of charmed baryons, i.e. $Λ_{c}^{+}\to pπ^{0},\,pη$; $Λ_{c}^{+}\toΛπ^{+}η,\,Σ^0π^{+}η$ and intermediate processes $Λ_{c}^{+}\toΛ(1670)π^{+},\,ηΣ(1385)^+$; $Ξ_c^0\toΛ\bar{K}^{*0},\,Σ^0\bar{K}^{*0}$ and $Σ^+K^{*-}$. (3) properties of excited charmed baryons, i.e. search for electromagnetic transition $Ξ_c(2790,2815)^{+,0}\toΞ_c^{+,0}γ$; and determination of spin-parity of $Ξ_c(2970)^+$.
