The origin of writing is a complex and multi-layered issue, involving many aspects such as the history, culture, religion and technology of human society. Regarding the origin of writing, there are several main theories as follows:
First of all, the rope knot theory believes that the origin of writing can be traced back to the way people used ropes to record things in ancient times. In ancient society, people used ropes of various colors or tied knots on the ropes to record dates, events, counts, etc. This way of recording was widely used in ancient society and was also a primitive form of writing.
Secondly, the Shuqi theory believes that the origin of writing can be traced back to ancient people using knives to carve words on bamboo or wood chips. This way of recording has the advantages of being difficult to change and having a long storage time. Therefore, it gradually became the main way of recording events in ancient society, and various writing systems gradually evolved.
The third theory is the picture theory, which believes that the origin of writing can be traced back to ancient people using pictures to record things. In ancient society, people used various simple pictures or pictographic symbols to record things. Over time, this way of recording gradually evolved into various writing systems, such as hieroglyphics, oracle bone inscriptions, bronze inscriptions, etc.
In addition to the above three theories, there are also different theories such as oracle bone script theory, bronze script theory, seal script theory, official script theory and regular script theory. Oracle bone inscriptions are said to be characters carved on tortoise shells and animal bones with knives by the Shang Dynasty, and are the earliest systematic writing in my country; bronze inscriptions are said to be inscriptions cast on bronze vessels; seal script is said to be a font of Chinese characters with neat shapes. .
The official script is a font of Chinese characters, which is simplified from the seal script; the regular script is the standard font of modern Chinese characters. The origin of writing is a complex and multi-layered issue, involving many aspects such as the history, culture, religion and technology of human society. Different cultural and social backgrounds may have an impact on the origin of writing, so we need to comprehensively study this issue from multiple perspectives.
