In addition to the two main spoken dialects of Chinese, there are also two different writing systems that affect Chinese translations.
Traditional Chinese characters are based on a writing system established in the 2nd century AD. These characters are still used in Taiwan, Hong Kong, and Macao, as well as in many communities in the global diaspora.
To improve literacy in the 1950s, the Chinese government created a streamlined set of commonly used characters. Today, these are referred to as Simplified Chinese. They are the characters taught in mainland Chinese schools and used in modern government documents. Additionally, Chinese-speaking communities in Malaysia and Singapore adapted the same set of characters.
Both styles of characters are written left-to-right when used in a contemporary context, such as a newspaper or a website. However, in historical documents, they were read from the right to the left of a page in columns that ran from top to bottom.
Because Simplified Chinese was developed by the government of China, Traditional Chinese is viewed by many Taiwanese as a marker of national pride and identity.
