The BESIII experiment, running at 2–4.6GeV center-of-mass energy, has collected the largest ψ' and J/ψ samples. New results using the data collected by the BESIII detector are presented, which include the measurement of the spin singlet state hc(1P) from ψ' decays, the χc0 and χc2 decays into π0π0 and ηη and the χcJ decays to vector meson pairs (ωω, φφ, ωφ). We also confirmed the p¯p threshold enhancement, which was observed in J/ψ → γp¯p at BESII, from the decays of ψ' → π+π− J/ψ(J/ψ → γp¯p) and J/ψ → γp¯p, respectively. The X(1835) is confirmed too in J/ψ → γη' π+π−.
