The ten-book series is Vietnam’s first publication to provide Vietnamese children with some awareness of the island sovereignty issue.
The story line was based on official documents, and includes historical details related to Vietnam's Hoang Sa and Truong Sa archipelagos.
The content focuses on four children named Ti, Suu, Dan and Meo. The books were designed to instill a fondness for learning about Vietnam’s sovereignty over its sea and islands through lively illustrations.
The Phan Thi company of Ho Chi Minh City is expected to publish further volumes of the series on a quarterly basis.
