\begin{document}$ X_0 $\end{document}(2900) and \begin{document}$ X_1 $\end{document}(2900) with unknown parity. Inspired by the report, we consider all the possible four-quark candidates for X(2900), which include the molecular structure, diquark structure, and their coupling in a chiral quark model via the Gaussian expansion method. To identify the genuine resonances, the real-scaling method (stabilization method) was employed. Our results show that five possible resonances, \begin{document}$ R_0(2914) $\end{document} with \begin{document}$ \Gamma = 42 $\end{document} MeV, \begin{document}$ R_1(2906) $\end{document} with \begin{document}$ \Gamma = 29 $\end{document} MeV, \begin{document}$ R_1(2912) $\end{document} with \begin{document}$ \Gamma = 10 $\end{document} MeV, \begin{document}$ R_J(2920) $\end{document} with \begin{document}$ \Gamma = 9 $\end{document} MeV, and \begin{document}$ R_J(2842) $\end{document} with \begin{document}$ \Gamma = 24 $\end{document} MeV, originate in the \begin{document}$ cs\bar{q}\bar{q} $\end{document} system. Compared with experimental data, \begin{document}$ R_0(2914) $\end{document} with \begin{document}$ \Gamma = 42 $\end{document} MeV may be an optimal \begin{document}$ X_0(2900) $\end{document} candidate. However, none of the resonances have a similar width for \begin{document}$ X_1(2900) $\end{document}. Hence, further study is required."> <i>X</i>(2900) in a chiral quark model -
