Who knows Bing Xin's poem "Mission"?

One spring morning—

A moving car:

The drizzle sprinkled on the ancient wall,

Sprinkle with willows,

I am a little aware of my mission.

One summer night—

A waterstop courtyard:

The sunset glow shines on the bamboo canopy,

According to Sophora japonica,

I am deeply aware of my mission.

Consciousness recognition,

Try to look back!

Is it joy or melancholy?

It's been two years!
