Mr. $PI , looking back, the light boat has passed through ten thousand mountains; looking forward, the road ahead is long and radiant; looking up, the fireworks of the world are dazzling; looking down, the thorns along the way are more than half gone. You need to endure, endure until the bitterness turns to sweetness; you need to wait, wait until spring warms and flowers bloom. May there be a path beneath your feet, light in the distance, and as you step forward, your grand vision unfolds!
