Likely member stars were identified based on a membership probability threshold ($P \\geq 0.5$), resulting in 106 and 146 members for CWNU 2666 and HSC 224, respectively. The mean proper motion components ($\\mu_{\\alpha}\\cos\\delta$, $\\mu_{\\delta}$) were determined to be (0.646$\\pm$0.155, -0.769$\\pm$0.124) mas yr$^{-1}$ for CWNU 2666, and (0.665$\\pm$0.131, -0.728$\\pm$0.107) mas yr$^{-1}$ for HSC 224.
