components [@ballesteros99; @heitsch08; @vazqez07] or the collision of two clouds [@elmegreen98]. Massive OB-stars are the important sources of mechanical and radiative energy, and can impact their surroundings through their intense energetic feedback (i.e., stellar wind, ionized emission, and radiation pressure). However, the stellar feedback cannot explain the existence of multiple velocity components in the selected physical system [see also @kohno18].

Concerning the “cloud cloud collision" (CCC) process, @habe92 studied numerical simulations of a head-on collision of two non-identical clouds. The simulations develop gravitationally unstable cores/clumps at the interface of the clouds due to the effect of their compression. In the CCC process, young stellar clusters and massive stars can be formed at the intersection of two molecular clouds or the shock-compressed interface layer [e.g., @habe92; @anathpindika10; @inoue13; @takahira14; @haworth15a; @haworth15b; @torii17; @bisbas17 and references therein]. In the CCC site, one may observationally find the spatial and velocity connections of two molecular clouds [e.g., @torii17; @dewangan17x; @dewangan17xx; @dewangan17b; @dewangan18b; @dewangan19a]. In the position-velocity map, one may also trace bridging features between two molecular clouds, which enable us to infer the association of the two clouds [e.g., @haworth15a; @haworth15b]. It may also hint the presence of a compressed layer of gas due
