There are so many countries and people in the world, so many customs, traditions, and beliefs. All of them have their roots in ancient times, and today may seem strange, incomprehensible, and not always appropriate. Nevertheless, all of them have their own hidden, secret meaning, so they are carefully preserved and passed down from one generation to another. For example, indigenous Samoans have a tradition of sniffing each other when they meet. This allows them to find out where a person came from, when they last ate, and if they are a stranger. Every nation has its own traditions, customs, and rites. Some seem quite adequate, while others seem strange. Take a test and see how well you know the traditions of the world.
