Traditional Chinese characters (; Pinyin: Zhèngtǐzì/Fántĭzì ) are Chinese characters in any character set that does not contain newly created characters or character substitutions performed after 1946.

The Zhengma Input Method (Simplified Chinese: 郑码输入法, Traditional Chinese: 鄭碼輸入法) (also referred to as Zheng code method) is a Chinese language input method.
 The primary goal of Zhengma design is compatibility with different types of characters (ability to input both simplified Chinese and traditional Chinese), scalability (it works well with extremely large sets of ideographs) and ease of use, especially for people who are experienced with how ideographs are formed.
 For these reasons this input method is used more by scholars of the Chinese language or people who need to use both traditional and simplified Chinese.
 This input method is one of two stroke-based input method that are included with Microsoft Windows.
 (The other stroke-based method is Cangjie which can also generate both simplified and traditional characters and which is extensively taught and used in Taiwan and Hong Kong.)

The second round of Chinese character simplification, according to the official document, Second Chinese Character Simplification Scheme (Draft) ("Second Scheme" or "Second Round" for short) to introduce a second round of simplified Chinese characters, was an aborted orthography reform promulgated on 20 December 1977 by the People's Republic of China (PRC).
 It was intended to replace the existing (first-round) simplified Chinese characters that were already in use.
 The complete proposal contained a list of 248 characters that were to be simplified, as well as another list of 605 characters for evaluation and discussion.
 Of these, 21 from the first list and 40 from the second served as components of other characters, amplifying the impact on written Chinese.

Kyūjitai (舊字體/旧字体 , literally "old character forms") , are the traditional forms of kanji, Chinese written characters used in Japanese.
 Their simplified counterparts are shinjitai (新字体 ), "new character forms".
 Some of the simplified characters arose centuries ago and were in everyday use in both China and Japan, but they were considered inelegant, even uncouth.
 After World War II, simplified character forms were made official in both these countries.
 However, in Japan fewer and less drastic simplifications were made: e.g. "electric" is still written as 電 in Japan, as it is also written in Hong Kong, Macao, South Korea and Taiwan, which continue to use traditional Chinese characters, but has been simplified to 电 in mainland China.
 Prior to the promulgation of the Tōyō kanji list in 1946, kyūjitai were known as "seiji" (正字 ; meaning "proper/correct characters") or "seijitai" (正字體 ).
 Even after "kyūjitai" were officially marked for discontinuation with the promulgation of the Tōyō kanji list, they were used in print frequently into the 1950s due to logistical delays in changing over typesetting equipment.
 "Kyūjitai" continue in use to the present day because when the Japanese government adopted the simplified forms, it did not ban the traditional forms.
 Thus traditional forms are used when an author wishes to use traditional forms and the publisher agrees.
