The mass spectrum and strong decays of the X(1870) and η2(1870) are analyzed. Our results indicate that X(1870) and η2(1870) are the two different resonances. The narrower X(1870) seems likely a good hybrid candidate. We support the η2(1870) as the η2(21D2) quarkonium. We suggest to search the isospin partner of X(1870) in the channels of J/ψ⟶ρf0980π and J/ψ⟶ρb11235π in the future. The latter channel is very important for testing the hybrid scenario.
