There was no concept of "national anthem" in Han Dynasty.
PS: Song of the Wind is a masterpiece full of boldness and simplicity. In BC 196, Emperor Gaozu Liu protested against the rebellion of King Huainan. On his way home, he invited his old friends and brothers from his hometown through Pei County. During the dinner, 120 people sang with him. The atmosphere was very warm, and he drank with everyone. At the banquet, he sang this popular song, expressing his political ambition and anxiety about state affairs.
