Unity and natural disasters
Every kind of natural disaster can be found in the oracle bones of the Yin ruins, such as: droughts, floods, earthquakes, windstorms, thunder storms, locust plagues, also solar eclipses and lunar eclipses, because the Shang people also saw these astronomical phenomena as natural disasters. If we say that the oracle bone inscriptions are the source of the Chinese people's characters, then we can say that anxiety about natural disasters is one of the motive forces behind the coming into being of Chinese characters.
