There are 4 characters at the beginning of the paragraph, and each word is followed by 1 characters. Capitalize the letter at the beginning of the sentence. Punctuation marks use one character (half-width, western punctuation). There is no alternation between sentences and paragraphs. If you can't finish writing a line, you should follow the rule of complete syllables and continue writing on a new line with "-"before the character.

The character size and the number of characters per line are determined according to the requirements of the paper.
