Phạm Hùng, Secretary of the Central Office of South Vietnam (COSVN), outlined the requirements about the ordered anthem:[1][2] Mai Văn Bộ and Huỳnh Văn Tiểng wrote the lyrics and Lưu Hữu Phước composed the music.

However, the printing houses mistook the word "L" for "S", hence the pseudonym was mistakenly published as "Huỳnh Minh Siêng".

The author trio decided to left the misspelled pseudonym as it is because "Siêng" (meaning "diligent") was considered to be a good name.

[2] The anthem received positive feedback from the local members and the central body of the National Liberation Front of South Vietnam.

[1] Giải phóng miền Nam, chúng ta cùng quyết tiến bước.

Diệt Đế quốc Mỹ, phá tan bè lũ bán nước.

Ôi xương tan máu rơi, lòng hận thù ngất trời.

Thúc giục đoàn ta xung phong đi giết quân thù.

To liberate the South, we determined to advance, To exterminate the American imperialists, and destroy the country sellers.
