A full stop in the history of China.
In the Han Dynasty, some people used the method of "retaining classics" to break words. That is, write a word or two between two sentences, or mark the end of a sentence with a vertical line or a short horizontal line, but it is not used much.
The Book of Rites compiled by Dai Sheng in the Western Han Dynasty said, "Enter the school in the next year, take the exam in middle age, and read the classics and distinguish the records in one year". Zheng Xuan's Note: "You can't break sentences without classics." . At that time, when reading, people often marked "し" next to sentences as a reading aid. This is the bud of punctuation. There were two sentence reading symbols in the Eastern Han Dynasty: "↓" and ",".
Xu Shen explained in Shuowen Jiezi in the Eastern Han Dynasty that "↓" means "hooking knowledge, living in the moon and cutting" and "stopping at it, knowing it and taking care of it". That is to say, all the places that can be stopped at the end of the text are marked with "↓", and the places where sentences can be read in the text are marked with ",",which is roughly equivalent to the period and comma in modern Chinese.
