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. $D^{0}\to\pi^{+}\pi^{-}\eta,\,K^{+}K^{-}\eta$ and $D^{0}\to\phi\eta$; $D_{s}^{+}\to K^{+}\pi^{0},\,K^{+}\eta$ and $D_{s}^{+}\to\pi^{+}\pi^{0},\,\pi^{+}\eta$.
(2) the branching fractions for the decays of charmed baryons, i.e. $\Lambda_{c}^{+}\to p\pi^{0},\,p\eta$; $\Lambda_{c}^{+}\to\Lambda\pi^{+}\eta,\,\Sigma^0\pi^{+}\eta$ and intermediate processes $\Lambda_{c}^{+}\to\Lambda(1670)\pi^{+},\,\eta\Sigma(1385)^+$; $\Xi_c^0\to\Lambda \bar{K}^{*0},\,\Sigma^0\bar{K}^{*0}$ and $\Sigma^+ K^{*-}$.
(3) properties of excited charmed baryons, i.e. search for electromagnetic transition $\Xi_{c}(2790,2815)^{+,0}\to\Xi_c^{+,0}\gamma$; and determination of spin-parity of $\Xi_{c}(2970)^+$.
