The Ngonso Legacy. The Nso people occupy parts of the Bui Division of the North West Region of Cameroon. They share the same ancestry with the Bamoum people of West Region. They attach a lot of importances to their traditional values and institutions. One of those pillars of the Banso ( people of Nso) is the Ngonso Festival. On CRTV this Monday at 10:30 am watch a 26 minute documentary from CRTV Northwest regional bureau on The Legacy of Ngonso.
