China ancient traditional symbols

The punctuation marks in ancient China were generally abbreviated as "sentence reading". Sentences, marked "○", are equivalent to the full stop used today, which are divided into large, medium and small; Read (d à u), marked ",",which is equivalent to the comma used today. In fact, in the long history of civilization development in China, there are more than two kinds of punctuation marks used by predecessors, but they have not accumulated and developed into a unified and standardized system. Even the division of labor between "sentence" and "reading" symbols is irregular and may even be unnecessary. Modern China people, if they hold up ancient books without modern punctuation without special training, even if they can read words with the help of reference books, it is very sad to "break sentences". The problem is that there are no or too few punctuation marks.
