Unlocking the ban on traditional Chinese characters means lifting the ban.
As follows:
Traditional Chinese characters, also known as Traditional Chinese, are called Traditional Chinese in European and American countries. They generally refer to Chinese characters that have been replaced by simplified characters during the simplification movement of Chinese characters. Sometimes it also refers to the entire Chinese regular script and official script writing system before the Chinese character simplification movement. Traditional Chinese has a history of more than three thousand years, and until 1956 it was the standard Chinese character commonly used by Chinese people everywhere.
The large-scale simplification movement of Chinese characters in modern times began in the Taiping Kingdom. Simplified characters mainly came from the regular script of ancient characters, popular characters, variant characters, running script and cursive script of all dynasties.
In 1935, the Ministry of Education of the National Government of the Republic of China promulgated the "First Batch of Simplified Chinese Character Lists", but it was shelved due to the opposition of Dai Jitao, the director of the Examination Yuan. On January 28, 1956, the State Council of the People's Republic of China issued the "Resolution on the Announcement of the "Chinese Character Simplification Plan", and mainland China began to fully implement simplified characters. In the 1970s, there were a batch of two simplified characters, and later was abolished.
The regions that still use traditional Chinese characters include China’s Taiwan region, Hong Kong Special Administrative Region and Macao Special Administrative Region. Countries in the Chinese character cultural circle, overseas Chinese communities such as Singapore and Malaysia mostly use traditional and simplified characters. In mainland China, traditional Chinese characters coexist. Traditional Chinese characters should be retained or used for cultural relics, surname variations, calligraphy and seal cutting, handwritten inscriptions, and special needs.
