The People’s Public Security Publishing House introduced two documentary books in Hanoi on April 22 on the occasion of the 40 th anniversary of South Vietnam liberation and national re-unification.

The book “Nhung ngay o chien truong- Tap 3” (Battlefield Days – part three) features portraits of public security officers who joined the fighting on the southern battlefield before 1975.

Another book, “Nhung la thu thoi chien Vietnam” (Letters during the Vietnamese war), took 10 years to complete (2005-2015) and introduces over 100 letters of war veterans, invalids and martyrs sent to their families and relatives during the anti-US war. They are among thousands of letters collected by writer Dang Vuong Hung, who initiated a campaign to collect items and documents related to the war.

Speaking at the event, Director-Chief Editor of the People’s Public Security Publishing House Nguyen Hong Thai said the introduction of the books is intended to commemorate former generations who sacrified their lives for the nation’s reunification and enhance the younger generation’s patriotism.-VNA
