In total, 459 outflow candidates were identified. Approximately 62\\% (284) were located in the Perseus arm, including W3/4/5 complex and its surroundings, while $\\sim$ 35\\% (162) were located in the Local arm, $\\sim$ 1\\% (5) in the Outer arm, and $\\sim$ 2\\% (8) in two interarm regions. This result indicated that star formation was concentrated in the Galactic spiral arms.
