过往 (guò wǎng): to come and go; to associate with; to have dealings with; the past; former times

Outside the window, the sound of vehicles coming and going gradually faded, and the late-night city finally quieted down.

This old street has recorded the comings and goings of countless pedestrians; every stone slab hides a different story.

Standing on the bridge, I watched the boats coming and going below, thinking of my family far away.

In life, joy and sorrow are always coming and going; we must learn to cherish every moment in front of us.
