What are China's classical poems and modern and contemporary classics that reflect the national spirit and the spirit of the times?

Yue Fei's "Full of Jiang Hong, Angry at the Crown"

Angry, leaning on the railing, resting in the rain. Looking up, screaming in the sky, strong and fierce. Thirty fame, dust and earth, eight thousand miles of clouds and the moon. Don't be idle, white and sad! Jingkang shame, still not snow; When will courtiers hate it? Driving a long car, breaking through the lack of Helan Mountain. Eat pork when you are hungry, and drink Hun blood when you are thirsty. Stay from the beginning, clean up the old mountains and rivers, and go to the sky!

From Xing Jun, Wang Changling

There is a dark snow-capped mountain in Qinghai, with long white clouds and a lonely city looking at Yumenguan. Yellow sand wears golden armor in hundreds of battles, but the loulan is not returned.
