Tsonga/shangaan how do they spread death news

Shoshangana of the Shangaan Tribe died in 1858. Though this is the case, the death of Shoshangana was not announced until 1859 - a year after his death. After people found out that he died, his two sons fought for political power for six long years. Eventually, Muzila (one of the brothers) became the victor.
