Chinese punctuation for proper nouns

Modern versions of the Chinese language have two kinds of punctuation marks for indicating proper nouns: the proper name mark / proper noun mark (Simplified Chinese: 专名号; Traditional Chinese: 專名號) and the book title marks / title marks (Simplified Chinese: 书名号; Traditional Chinese: 書名號). The former may be applied to all proper nouns except when the nouns in question are titles of textual or artistic works, in which case the latter are used instead.
