Do you know something about the Akuapem people? They live in eastern Ghana (加纳), where the sunshine hugs all the time. They are very friendly. Now let’s have a look at how the Akuapem people receive a visitor.

A visitor is often welcomed warmly in a family of Akuapem. After the visitor is welcomed into the house, he is offered a seat and water at the very beginning, for the host (主人) thinks that the visitor must have come from a very long trip and is in need of water. Then the host family greet the visitor by saying “Akwaaba.” More interestingly, if there is a group of visitors, the host will greet the visitors from right to left. And the host shakes only with his right hand, because the left hand is regarded dirty according to the Akuapem people.

Next, the visitor is asked how his trip was and why he has come. While the conversation is going on, the wife and children, especially girls, are cooking food for the visitor. The visitor can choose the food. After the visitor has finished eating, the host and the visitor continue their conversation. Usually this is a short one since the visitor is getting ready to say goodbye.

When the visitor is leaving, he is often given some food to take along. He is also accompanied (陪伴) by one of the children to the nearest station. The child who accompanies the visitor will not come back home until the visitor leaves safely.

No matter if he is a close friend or just a passer-by (过路人), this is always the way that the friendly Akuapem people receive a visitor.
