Knowledge about the origin of words.
1, about the origin of characters, there is a general view that "demand creates supply". In order to record their thoughts, activities and experiences, people began to create some marks and symbols. At first, these symbols may be simple images or graphics, and then gradually develop into more complex writing systems.
In ancient Egypt, hieroglyphics were used to record myths, religious ceremonies, trade and historical events. These hieroglyphs are carved on stones, pyramids, temple walls and tombs. With the passage of time, these hieroglyphs have been gradually simplified and developed into a more easy-to-use writing system.
In ancient China, Oracle Bone Inscriptions was one of the earliest characters. Oracle Bone Inscriptions is a hieroglyphic carved on tortoise shells and animal bones, which is mainly used to record the ancient history and religious events in China. With the passage of time, Oracle Bone Inscriptions gradually evolved into a more systematic way of writing, called seal script.
The origin of writing is a complicated and fascinating process, which involves the development of human culture, history and technology. Although we can't determine the exact time of the origin of characters, we can understand the diversity of this process through different evidences and cultures.
