On March 16, 1968 morning, 504 Son My residents, mostly the elderly, women and children, were killed brutally. Since then, Son My became an inconsolable pain of the entire Vietnamese people and others of conscience around the world. The Son My massacre is not the only but a typical case of the brutal crimes that warlike forces committed against people of Quang Ngai and Vietnam during wartime, and it is also typical for the ultimate pain Vietnamese people suffered from. The 55th anniversary of the massacre is an occasion to commemorate the victims, pray for peace, and more importantly, take practical actions to heal the wounds of the past and develop the life to ensure happiness for all. The mass killing, also called the My Lai massacre, took its name from one of the four hamlets where it happened./.
