We investigate the three open clusters near Aquila Rift cloud, named as UPK39 (\texttt{c1} hereafter), UPK 41 (\texttt{c2} hereafter) in Sim et al. (2019)and PHOC 39 (\texttt{c3} hereafter) in Hunt \& Reffert (2021), respectively.Using photometric passpands, reddening, and extinction from Gaia DR3, weconstruct the color-absolute-magnitude diagram (CAMD). Using isochrone fitstheir ages are estimated as $6.3\pm0.9$, $8.1\pm1.4$ and $21.8\pm2.2$ Myr,respectively. Their proper motions and radial velocities, estimated using datafrom Gaia and LAMOST are very similar. From their orbits, relative distancesamong them at different times, kinematics, ages, and metallicities, we concludethat \texttt{c1} and \texttt{c2} are primordial binary open cluster, which arelikely to have been formed at the same time, and \texttt{c3} may capture\texttt{c1}, \texttt{c2} in the future.
