I love this land, and I chose several vivid poetic images to write the whole poem. What unique symbolic significance does the poet give these images?

There are four images, namely "the land hit by the storm", "the river of grief and indignation", "the wind of anger" and "the incomparable gentle dawn". "Storm-hit land" refers to the motherland ravaged by Japan at that time. The "river of grief and indignation" refers to the river running on the land, which seems to be the grief and indignation that has been smoldering in people's hearts for a long time. The "angry wind" symbolizes people's anger at the atrocities of the invaders. This "incomparably gentle dawn" refers to the party. The author thinks that China's * * * production party can liberate China and place hope and trust on China's * * * production party.
