We study the $Y(2175)$ using the method of QCD sum rules. There are twoindependent $ss\bar s\bar s$ interpolating currents with $J^{PC} = 1^{--}$, andwe calculate both their diagonal and off-diagonal correlation functions. Weobtain two new currents which do not strongly correlate to each other, so theymay couple to two different physical states: one of them couples to the$Y(2175)$, while the other may couple to another state whose mass is about $71^{+172}_{-~48}$ MeV larger. Evidences of the latter state can be found in theBaBar, BESII, Belle, and BESIII experiments.

A possible partner state of the $Y(2175)$
