Your last question was about the marks you call round and square brackets.

你的最后一个问题是关于你所说的圆方的标点。

So those are the pronunciations of those symbols, period, question mark, exclamation point, parentheses, brackets, colon, and semicolon.

所以这些是那些符、句、问、感叹、圆、方、分的发音。

I hope you can tell me about the difference between punctuation marks such as the semicolon, the colon and the comma and between round brackets and square brackets.

我希望你能告诉我分、逗之间的区别，以及圆方之间的区别。

It is used to separate groups of words when, as the writer, you want to emphasize a statement...or use them in place of a colon...or to replace parentheses or a commma.

当你想要强调一项陈述时，它被用来分开一组单词，它们也可以代替或圆或逗。

Parentheses are round, almost like the letter " O" but only half of it, and you put the first half before the sentence and the last half at the end of the sentence or phrase.

圆是圆的， 几乎像字母“O” ，但只有一半，前半部分放在句子之前， 后半部分放在句子或短语的末尾。
