When did the Chinese writing system develop?
Language
The invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late 4th millennium BC. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered to be the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400–3200 BC with the earliest coherent texts from about 2600 BC. It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or was a case of cultural diffusion. A similar debate exists for the Chinese script, which developed around 1200 BC. The pre-Columbian Mesoamerican writing systems (including among others Olmec and Maya scripts) are generally believed to have had independent origins.
China
Chinese characters have been used as the written script for the Sinitic languages for thousands of years. They allow speakers of mutually unintelligible Chinese varieties to communicate with each other through writing. In 1956, the government introduced simplified characters, which have supplanted the older traditional characters in mainland China. Chinese characters are romanized using the Pinyin system. Tibetan uses an alphabet based on an Indic script. Uyghur is most commonly written in Persian alphabet based Uyghur Arabic alphabet. The Mongolian script used in China and the Manchu script are both derived from the Old Uyghur alphabet. Zhuang uses both an official Latin alphabet script and a traditional Chinese character script.
