First of all, look at the theme of the competition you participated in. Second, look at what font you write. Soft pen: cursive script suggests that you write (giving people a visual fluency and elegance, miscellaneous but not messy). You can write poems and words in running script (fluency is one thing, neatness is not lost). If there is no requirement for the content of the book in the competition, you'd better write the chapters that you are most familiar with, the most fluent, the most beautiful glyph structure and the best layout. In addition, the printing volume can not be ignored. In my humble opinion, you can write horizontally or vertically. If you write horizontally, there is no special requirement for the format. Generally, you can use punctuation marks to write in two blank spaces, and then you can finish writing your signature. According to the number of spaces left in the last line, the rest are written in the last line and the rest are written in another line.
