Since they are located close to the mass thresholds of $\\bar{D}D_{1}$ and $\\bar{D}^*D_{1}$, they can be viewed as $\\bar{D}D_{1}$ and $\\bar{D}^*D_{1}$ molecules. Furthermore, recent studies indicated that the exotic states $X(3872)$/$Z_c(3900)$ and $X_2(4013)$/$Z_c(4020)$ are the isoscalar/isovector $\\bar{D}D^{*}$ and isoscalar/isovector $\\bar{D}^*D^{*}$ molecules, respectively.
