  Open Clusters are born and evolve along the Milky Way plane, on them is
imprinted the history of the Galactic disc, including the chemical and
dynamical evolution. Chemical and dynamical properties of open clusters can be
derived from photometric, spectroscopic, and astrometric data of their member
stars. Based on the photometric and astrometric data from the Gaia mission, the
membership of stars in more than 2000 Galactic clusters has been identified in
the literature. The chemical and kinematical properties, however, are still
poorly known for many of these clusters. In synergy with the large
spectroscopic survey LAMOST (data release 8) and Gaia (data release 2), we
report a new comprehensive catalogue of 386 open clusters. This catalogue has
homogeneous parameter determinations of radial velocity, metallicity, and
dynamical properties, such as orbit, eccentricity, angular momenta, total
energy, and 3D Galactic velocity. These parameters allow the first radial
velocity determination and the first spectroscopic [Fe/H] determination for 44
and 137 clusters, respectively. The metallicity distribution of majority
clusters shows falling trends in the parameter space of the Galactocentric
radius, the total energy, and the Z component of angular momentum -- except for
two old groups that show flat tails in their own parameter planes. Cluster
populations of ages younger and older than 500 Myrs distribute diversely on the
disc. The latter has a spatial consistency with the Galactic disc flare. The
3-D spatial comparison between very young clusters (< 100 Myr) and nearby
molecular clouds revealed a wide range of metallicity distribution along the
Radcliffe gas cloud wave, indicating a possible inhomogeneous mixing or fast
star formation along the wave. This catalogue would serve the community as a
useful tool to trace the chemical and dynamical evolution of the Milky Way.
