Poetry praising the motherland should have a title and an author.

Singing: Zu Hai's "For Who", Zu Hai's singing mud, pants legs are sweaty, clothes are soaked. I don't know who you are, but I know who you are for, who you are for, who you are for, who you are for, who you are for, who you are for, my brothers and sisters don't cry, who you are the most beautiful, who you are the most tired, my comrades, my brothers and sisters.
