The Usage of Punctuation Marks (GB/T15834-2011) has been adopted as a national standard for many years; however, certain areas may benefit from further improvement. The main points are as follows: firstly, it is advisable to add an introduction to the dot mark “.”; secondly, it would be beneficial to expand the scope of the book title mark; thirdly, establishing a proper noun mark in modern Chinese texts is recommended; and fourthly, the repeated use and combination of question and exclamation marks should take into account the punctuation practices of ancient Chinese literature.
