Query: Review on low and high mass spectroscopy   We review the most recent experimental progress in the hadron spectroscopy,
up to bottomonium mass. This covers the search for the J^PC=1^-+ exotic state,
the states in J/psi decays, the spin-singlets of heavy quarkonium, and the
charmoniumlike XYZ states.
