I am wandering in the battlefield today. I feel a feeling heart and give birth to white hair prematurely. (Tell me what this means)

Wandering in the battlefield of the old country (Three Kingdoms), you have to laugh at my excessive sadness and premature birth of white hair.

"My hometown is falling, my passion is Ying Xiao Wo, and I am born early and prosperous"-from here, I turn to my personal feelings. Roaming in the Old Country refers to Battle of Red Cliffs in the Three Kingdoms and those historical figures, which caused many feelings-as if his soul had traveled through ancient times. "Affection" is to laugh at your own affectation. Because of self-love, it is inevitable to have early hair (white hair), so I have to laugh at myself. Here, the author can't make a career for himself, and he is old-compared with Zhou Yu, who was only 34 years old when he broke Cao Cao, he was still singing in Chibi Mountain, which is deeply touching.
