associated with AFGL 5157, Figures \[fig4\]a and \[fig4\]b show the $^{12}$CO(J =1$-$0) and $^{13}$CO(J =1$-$0) intensity maps (moment-0) integrated over a velocity range of $-$22 to $-$15 km s$^{-1}$, respectively. The locations of the filamentary feature, infrared shell, and previously known H[ii]{} region are highlighted in both the molecular maps. We find that all the [*Herschel*]{} filaments are embedded in the molecular cloud associated with AFGL 5157. Note that our molecular line data, having coarse resolutions, do not allow to trace the gas motions along/into the filamentary structures seen in the [*Herschel*]{} data. However, these molecular line data enable us to study the large-scale molecular cloud motions. The observed $^{12}$CO and $^{13}$CO profiles are presented in Figure \[fig4\]c. The spectra are produced by averaging the area highlighted by a solid circle in Figure \[fig4\]b, which is located toward the the central part of the filamentary feature. The $^{12}$CO profile reveals two velocity peaks (around $-$20 and $-$17 km s$^{-1}$), while a broad profile of $^{13}$CO is observed toward our selected area (see a solid circle in Figure \[fig4\]b). Figure \[ufig4\] displays the average $^{12}$CO and $^{13}$CO spectra in the direction of twelve small regions (i.e., p1 to p12; see corresponding
