Traditional Chinese characters are one type of standard Chinese character sets of the contemporary written Chinese. The traditional characters had taken shapes since the clerical change and mostly remained in the same structure they took at the introduction of the regular script in the 2nd century. Over the following centuries, traditional characters were regarded as the standard form of printed Chinese characters or literary Chinese throughout the Sinosphere until the middle of the 20th century, before different script reforms initiated by countries using Chinese characters as a writing system.
