 # Appendix 1：Further Study Materials
 
+First of all, congratulations 🎉 on reading this book! I hope this book has raised your interest in modern C++.
 
+As mentioned in the introduction to this book, this book is just a book that takes you quickly to the new features of modern C++ 11/14/17/20, rather than the advanced learning practice of C++ "Black Magic". The author of course also thinks about this demand, but the content is very difficult and there are few audiences. Here, the author lists some materials that can help you learn more about modern C++ based on this book. I hope I can help you:

 # Appendix 2：Modern C++ Best Practices
 
+In this appendix we will briefly talk about the best practices of modern C++. In general, the author's thoughts on C++'s best practices are mainly absorbed from [Effective Modern C++](https://www.amazon.com/dp/1491903996/ref=cm_sw_em_r_mt_dp_U_-ZgjDb81ERBNP) and [C++ Style Guide](http://zh-google-styleguide.readthedocs.io/en/latest/google-cpp-styleguide/contents/). In this appendix, we will briefly discuss and use the actual examples to illustrate the methods, and introduce some of **the author's personal**, **non-common**, **non-sensible** best practices, and how to ensure the overall quality of the code.

 # 附录 1：进一步阅读的学习材料
 
-首先，恭喜你阅读完本书 🎉 ！笔者希望本书有提起你对现代 C++ 的兴趣。
+首先，恭喜 🎉 你阅读完本书！笔者希望本书有提起你对现代 C++ 的兴趣。
 
 正如本书引言部分提到的，本书只是一本带你快速领略现代 C++ 11/14/17/20 新特性的读物，而非进阶学习实践 C++『黑魔法』的内容。笔者当然也想到了这个需求，只是这样的内容非常艰深，鲜有受众。在此，笔者列出一些能够帮助你在此书基础之上进一步学习现代 C++ 的资料，希望能够祝你一臂之力：
