  We systematically searched for open clusters in the solar neighborhood within
500 pc using pyUPMASK and HDBSCAN clustering algorithms based on {\it Gaia}
DR3. Taking into consideration that the physical size for most open clusters is
less than 50 pc, we adopted a slicing approach for different distance shells
and identified 324 neighboring open clusters, including 223 reported open
clusters and 101 newly discovered open clusters (named as OCSN, Open Cluster of
Solar Neighborhood). Our discovery has increased the number of open clusters in
the solar neighborhood by about 45\%. In this work, larger spatial extents and
more member stars were attained for our cluster sample. We provided the member
stars and the membership probabilities through the pyUPMASK algorithm for each
cluster and derived their astrophysical, age, and structural parameters.
