Recent results on the B handrons decays from the CMS experiment at the LHC are reported. The observation of the $\mathrm{B}^{0}\to\psi(2\mathrm{S}) \mathrm{K}^{0}_{\mathrm{S}}\pi^{+}\pi^{-}$ and $\mathrm{B}^{0}_{\mathrm{s}}\to\psi(2\mathrm{S}) \mathrm{K}^{0}_{\mathrm{S}}$ decays is presented together with the observation of a new beauty strange baryon decaying to $\Xi_{\mathrm{b}}^{0}\pi^{+}\pi^{-}$ and the first observation of the $\Lambda^{0}_{\mathrm{b}}\to \mathrm{J}/\psi\Xi^{-}\mathrm{K}^{+}$ decay. The results are based on data sample collected in pp collisions at 13 TeV.
