Hadron spectroscopy serves as an indispensable tool for exploring the nonperturbative aspects of Quantum Chromodynamics and the mechanism of confinement. There has been an exciting period of recent two years, during which a significant number of new hadrons, mainly exotic candidates, have been discovered, primarily in the BESIII and LHCb experiments. This talk review the progresses on the experimental studies of the light and heavy hadrons. High-statistics data become crucial for identifying the exotic features of known states and discovering new particles. In the future, the upgraded BEPCII-U, Belle II and LHC RUN 3 experiments would be promising in boosting the studies of hadron physics.
