Good work. I noticed you didn't change much, before we merge, could you please review it again and make sure everything is satisfactory to you? Thanks.

um, again all these I mentioned are optional.
overall its really accurate to the CN version. (I only went through the parts changed).
thank you for your hard work!

Hi YangXuanyi
all of these I'm mentioning are optional:
you can change "In this book, chapters marked with an * symbol are optional to read. If you are short on time or find them challenging, you may skip these initially and return to them after completing the essential chapters."
to ->
"In this book, chapters marked with an asterisk '*' are optional readings. If you have limited time or find them challenging to understand, you may initially skip these chapters and tackle them after completing the essential ones."

[YangXuanyi]

Thank you very much for your suggestion. Among your suggestions, I think this is worth learning from: "with an asterisk '*' are optional readings." I accept your suggestion. The rest is translated as I did before.

[YangXuanyi]

Thanks very much for your suggestion. I have given a point by point response as per your suggestion, please check.

[YangXuanyi]

干得好。我注意到你没有太大变化，在我们合并之前，你能不能再审查一下，确保一切都令你满意？谢谢。

Thanks for the suggestion. I'll review the entire document again to make sure it's correct.

Hi @YangXuanyi, it is not recommended to use force-pushing because it may break the commits' linear history, making it harder to track the changes.

[YangXuanyi]

@krahets Sorry. I'll be more careful in the future.

Thanks for the PR @YangXuanyi and the review @yuelinxin @K3v123 !
