  We investigate the three open clusters near Aquila Rift cloud, named as UPK
39 (\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, we
construct the color-absolute-magnitude diagram (CAMD). Using isochrone fits
their 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 data
from Gaia and LAMOST are very similar. From their orbits, relative distances
among them at different times, kinematics, ages, and metallicities, we conclude
that \texttt{c1} and \texttt{c2} are primordial binary open cluster, which are
likely to have been formed at the same time, and \texttt{c3} may capture
\texttt{c1}, \texttt{c2} in the future.
