Zulu
When you get to someone’s compound, you have to shout out a greeting to inform them about your arrival. The greeting is important for various issues: as a tradition set by Shaka Zulu indicating that you come in peace and to get the blessing and protection of the ancestors of that family.
This particular greeting is different from the usual street greeting because the men need to remove their hats and everyone has to face the compound before calling out the greeting.
