We present a new moving group clustered in kinematics, spatial position and
elemental abundances. Its spatial position is around the center of the Local
Arm of the Milky Way. A convergent point method was taken to select candidate
member stars.textbf{ Among 206 candidate member stars, 74 are
pre-main-sequence stars and some of them have stellar disks.} We presume those
pre-main sequence stars belong to Orion nebula. We suggest this moving group is
caused by density wave of the Local Arm passing by.
