The book is a collection of portraits and interviews with Professor Dang Hung Vo over the past 30 years, from the time he made his mark with GPS navigation technology until he retired but has always been concerned about "hot" issues of land and housing policies. The articles all exude the portrait of the "heterogeneous" professor who is loved by the people with scientific works that have made great strides for the geodetic and mapping industry, creating momentum for socio-economic development as well as maintaining sovereignty, security and defense.
