摘　　要：Twenty years have passed since the observation of the Xe3872Tas the first XYZ charmonium-like state.With the accumulation of experimental data,more and more new hadronic states have been discovered,inspiring extensive attention to exotic hadronic matter,including multiquarks,hybrid,and glueballs[1,2].Taking this opportunity,it is an appropriate time to build the“Particle Zoo2.0”version,which is the main task of the current study of hadron spectroscopy.More importantly,these joint experimental and theoretical efforts will further advance our understanding of the nonperturbative behavior of the strong interaction by these joint.In fact,representing the precision frontier of particle physics,hadron spectroscopy is entering the high-precision era.
