The early histories of many African countries are not certain. Ancient people didn't' write down things that happened. Instead, the older people told stories to the younger people. This is how history was passed down. Here is the story of a great king-Gihanga.

Rwanda（卢旺达）is country near lots of big lakes and forests. A long time ago, there were lots of small towns in this place. But the people in these small towns had simple ways of living, with little technology to help them. Back then, there was no country, no “Rwanda” in the world.

Gihanga is thought to have spent his childhood in different locations in Central Africa. It was said' that his father was a man of wealth and ability. Gihanga learned a lot from his father. He knew how to use metal to make things, like shoes for horses. People thought he was a clever boy.

Thanks to Gihanga's great mind, many people fell in love with him. He is believed to have discovered fire, invented new ways of farming（农耕）and building, and made new objects from metal. All of these things were introduced to local people to improve their lives. Besides all this, he may have also founded（建立）the country of Rwanda, made laws（法律）and spread religion（宗教）.

But can we be sure all this is true? The story of Gihanga has been told for thousands of years. How much of the story might have changed? Can we even be sure Gihanga existed（存在）at all?
