The image is a photograph of a plaque on a wall with the word "Preface" written in Chinese characters. The plaque is titled "Central Africa, on the south of the Sahara, is an untamed land with vitality. It is famous for the dense Congo rainforest, the immense tropical grassland, the amazing equator snow-capped mountain and abundant wild animals. The unique cultural beauty here is also astonishing, particularly that of the mysterious and charming traditional weapons. Traditional weapons were manufactured in Central Africa over two thousand years ago, and they didn't disappear in war until the huge input of firearms from Europe. The iron weapons are a representative of its high-smelling technology. In conjunction with iron smelting, the sexual and reproduction metaphors radiate a kind of mysterious power. The shape and pattern on the weapon not only reflects the unique art creativity and sense of beauty of the central African people but also serves as a representation of the social status of the user. The over 300 pieces of traditional weapons from Gabon, Congo, Sudan, Central Africa, Angola, Zambia, Rwanda, Burundi and Tanzania offer us a chance to appreciate the unique charm of foreign culture. Let's walk into the world of traditional African weapons and explore their mystery together."
