The masses and widths are estimated by assuming that the $X(4140)$ is the lower $1^{++}$ $cs\\bar{c}\\bar{s}$ tetraquark. Comparing our results with experimental measurements, we find that the recently observed $X(3960)$ by LHCb can be assigned as the lowest $0^{++}$ $cs\\bar{c}\\bar{s}$ tetraquark state and the $X_0(4140)$ could be the second lowest $0^{++}$ $cs\\bar{c}\\bar{s}$ tetraquark. Predictions of ratios between partial widths for the involved tetraquarks are given.
