2. When writing a composition, are double quotation marks and commas in one box? Yes
In addition, the correct way to write punctuation marks on the composition paper is as follows:

But these seven symbols can't be placed at the beginning of the line, because they indicate the pause of mood and should be placed at the end of the sentence. If the last cell of a line happens to be occupied by text, then this punctuation mark must be marked in the lower right corner of the text.
(2), quotation marks, brackets, the first half and the second half of the title of the book all occupy the position of a word. The first half can be placed at the beginning of the line, but it does not appear at the end of the line, and the second half does not appear at the beginning of the line. The occupancy mode is that the first half is written in the right half of a grid and the second half is written in the left half of a grid.
(3), dashes and ellipsis occupy the position of two words, which can be placed at the beginning of a line or at the end of a line, but a symbol cannot be divided into two paragraphs. The six points of ellipsis should be evenly written in two squares, which is more compact. The two ends of the dash cannot intersect the sides of two squares, which is relatively compact. When there is only one space left in the ellipsis or dash, don't divide the symbol into one line and one line and a half, and try to weigh the deletion or addition of words as much as possible to stagger the remaining spaces. Connectors and separators generally occupy the position of a word. The positions of these four symbols are written in the middle of the line.
(4) Bullets and proper names are marked at the bottom of the words.
