To be precise, in 1875 the Qing Dynasty's "Qing Dynasty's Traditional Chinese Characters" stipulated some Chinese characters as standard characters; because the standard characters prescribed by the Qing Dynasty had many strokes, they were called traditional Chinese characters. Before the Qing Dynasty, there was actually no distinction between traditional and simplified Chinese characters, only the common characters. Originally, each Chinese character had multiple ways of writing, but the "Qing Dynasty Imperial Traditional Chinese Characters" all chose the clumsiest and most complicated way of writing. The Qing Dynasty also changed and re-created characters many times, repeatedly changing and re-creating them. Starting from Kangxi of the Manchu Qing Dynasty, the "Qing Dynasty's official orthodox characters" were promulgated at regular intervals, forcing the subjects to comply, otherwise it would be a typo.
Among the 388 simplified characters published in the 1950s, 111 appeared in the Han Dynasty and before the Han Dynasty; 166 appeared in the Tang Dynasty and before the Tang Dynasty; from the Song Dynasty to the Qing Dynasty There are 175 that appeared in the Qing Dynasty and before the Qing Dynasty, 341 in the Republic of China and before the Republic of China, a total of 387. However, only one word appeared after 1949. Modify answer
