The new particle $D^{*}_{s1}(2700)^{+}$ has stimulated many attentions. Thereare different assignments of its inherent properties. It may be a $2^3S_1$,$1^3D_1$ or the mixture of $2^3S_1-1^3D_1$ $c\bar s$ $1^-$ state. Byconsidering its mass, decay modes, full width, production rate, and comparingwith current experimental data, we point out that there is another morereasonable assignment: $D^{*}_{s1}(2700)^{+}$ could be identified as tworesonances, one of which is a $2^3S_1$ state, another is a 1D state, and bothare $c\bar s$ $1^-$ states. The two states have very close masses, which arearound 2700 MeV, and both have broad decay widths. So in experiments, theoverlapping of $DK$ or $D^*K$ invariant mass distribution coming from theirdecays is found, but the current experiments could not distinguish these tworesonances and reported one particle.
