Second, matters needing attention
Quoting refers to quoting others' words in writing. Idioms, aphorisms, poems, etc. It also includes onomatopoeic words and transliteration words.

Quotation marks are an important punctuation mark, including quotation marks (indicated by "or") and quotation marks (indicated by "or").
Third, the origin
In 1897, Wang made ten kinds of punctuation marks in Pinyin Zipu, which were called "interpretation of numbers". 1906, the punctuation system formulated by Lu Taizhang in the textbook of China Alphabet has 15 symbols, including "quotation".
Hu Shi suggested that quotation marks in the form of ("") should be used in the article on sentence reading and writing symbols published in the first issue of Volume II of Science. The former is western-style and is not suitable for straight manuscripts; The latter is Japanese, which is suitable for straight draft.
Qian said in 19 18 that the western quotation mark ("") was used in Japan because it was not suitable for going straight.
At that time, because the writing and typesetting of characters were mainly straight, 19 19 "Proposal on Promulgating New Punctuations" decided to use square quotation marks. This form of quotation marks has been used for straight manuscripts until now.
When the manuscript is used horizontally, 195 1 year "Usage of Punctuations" stipulates that it is not nice to use quotation marks horizontally, so some people use western quotation marks (') (') and (') ("). After the mid-1950s, the layout of publications gradually changed to horizontal layout, and western quotation marks were often used in practice.
