Introduction to punctuation marks:

It is a kind of writing symbol, which is used to express the reading and tone of sentences. Punctuation marks are auxiliary symbols and part of written language, which are used to express pause, mood and the nature and function of words. Punctuation marks include labels and dots.

There is a pause before and after the sentence, and there is a certain sentence tone, indicating a relatively complete meaning. Pauses before and after or in the middle of a sentence are expressed by time intervals in spoken language and punctuation marks in written language. Punctuation marks are an integral part of written language and an indispensable auxiliary tool for written language, which can help people express their thoughts and feelings and accurately understand written language.

Chinese punctuation marks:

In ancient Chinese literature, punctuation marks are generally not added, but sentences are broken through language sense, mood auxiliary words and grammatical structure. ("sentence reading symbol" is added to the article: a period means the end of the sentence; Reading the number seems to be the current pause, which means the pause of tone), which often leads to ambiguity and misunderstanding of the words used in the article;

For example, Zhao Tianyang, a poet in the Qing Dynasty, has seven ways to explain the sentence "Stay on rainy days and stay in the future" (another way of saying it is that I am a guest, not me). There were no common punctuation marks in ancient Chinese, and19th century began to use it. As a sentence. In the 8th century, Japan used kickbacks and training points as punctuation system.

But in fact, China has had punctuation marks since the pre-Qin period, which can be seen from archaeological relics since the 20th century, but there is no unified standard for these symbols. For example, the symbol "└" can be seen in bamboo slips of the Warring States Period, which usually indicates the end of an article; Another example is the function of "▄", which combines modern commas and periods to express sentence breaks.

In the records of the ancients, the biography of He Ji in the Song Dynasty greatly praised He Ji: "Every reading has punctuation. The meaning is self-evident, needless to say. " As a matter of fact, as early as Oracle Bone Inscriptions and the Jin Dynasty, a rather peculiar punctuation mark sprouted in China.
