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和的标点。

Some more parentheses, some more curly braces.

多的圆，多的大。

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.

你能告诉分、冒和逗之间的区别，以及圆和之间的区别。

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，它们也可以代替冒或圆或逗。
