What is my oath in the land oath?

The author's oath to the land is:

Land, vilen, my hometown, you must be liberated! You must stand up! Because I promised her that I would come back to her. I promise I will go back. I must see a more beautiful hometown in front of me or in front of my grave, and I will wash away all her filth and shame with my tears. The author vowed to fight and die for his hometown.

This is a lyric prose, full of full and deep patriotic enthusiasm. The author's expression of this emotion is unambiguous. He expressed the pent-up feelings of the exiled youth in Northeast China after the September 18th Incident in fiery language, as if people could hear their heartbeat and feel their blood boiling.

Nostalgia for the homeland is a universal feeling, but the Kanto Yuan Ye, to which the author attached, was occupied by the Japanese invaders for ten years. For the author, it is a lost and beautiful home; For China people, it is a lost land on the complete map of the motherland. So homesickness has a strong patriotic color, which makes people sing for it.
