Schematic diagram of the scenario argued in this work. Evolution of a cloud with multi-scale hub-filament structures with increasing effects of feedback. Here we borrowed three pictures from Fig. 1 as the background, for demonstration only. The yellow lines are the filament skeletons identified in Zhou et al. (2022). Considering the competitive accretion scenario, the precursor of the protocluster is located in the central position of the hub. With the evolution of the protocluster, feedback from HII regions destroys the hub by mechanical force, i.e., the expanding HII regions push away and reshape the hub region, accompanied by the redistribution of small-scale dense structures that may be local hub-filament structures. We note that small-scale hub-filament structures were not directly identified in this work due to the limitation of the resolution.
