What does it mean that the golden hall and the jade horse make the flat land thunder and send blessings for reputation and the promise of Changchun style?

I think it looks like a poem, similar to a Buddhist poem. My personal analysis means: Jintang refers to the highest yamen, that is, the emperor, and Ma Yuling is a decree to mobilize the army. The first sentence is that the emperor ordered the transfer of troops, such as thunder on the ground, vigorous and strong execution. In order to stabilize the country, the recruited generals and sergeants thought that future generations would inevitably disagree and killed the enemy on the battlefield in exchange for hereditary titles. They died. The last sentence is a blessing from the spring breeze, which seems very sad and makes people cry. They died in the battle, just like hay, the soldiers in the iron camp all died, the next crop was collected again, the wildfire never completely consumed them, and they were tall again in the spring breeze. . . . I shed tears when I was alone.
