There are some words in Chinese that can't be punctuated, but they are easily misunderstood when connected together.
For example:
1, name and title of literary genre.
Such as: seven methods without title, full of red snow, novel snowy night.
2. Name and name of dynasty.
Such as: Shi Wengong in Song Dynasty and Simon Wang in Southern Dynasty.
3. The concept of affiliation.
Such as: Historical Records Family Confucius Family
This noun combination is easy to be misunderstood. In the past, when printing with type, it was handled by leaving appropriate blanks through typesetting. After the popularization of computers, blanks are usually ignored, so people introduced the western separator "processing". The function, like blank, is to prevent misreading.
