The author is attached to things and writes loosely on the surface, but in fact he writes about people. Write about people's perseverance, perseverance, integrity and heroism, and write about the spirit of that particular era that is not afraid of difficulties, full of masculinity, and the more frustrated and brave. "Heavy snow overwhelms pines, and pines stand tall and straight" is a great praise to our party and people and the spirit of the times. Perhaps it is the combination of the author's personality and the spirit of the times, the internal and external interaction, and the projection of the specific metaphor of Song Qing by * * * that makes this poem have an awe-inspiring atmosphere, which is touching to read and can best highlight Song Qing's character.
