关于模板中添加图片，表格双语标题的问题

我尝试在模板中使用**bicaption**宏包，解决图片，表格双语标题的问题。
代码参考了刘海洋《LaTeX入门》中p349中的部分代码：
```LaTeX
\documentclass{ctexart}
\usepackage{bicaption}
\DeclareCaptionOption{english}[]{%
\renewcommand\figurename{Figure}%
\renewcommand\tablename{Table}}
\captionsetup[bi-second]{english}
```
但模板中没有使用**ctexbook**，而采用**book**，对此，我并没有找到合理的办法使用双语标题。
编译环境：**TeX Live 2019，VS Code 1.64.2**
编译方法：**XeLaTeX ->BibTeX -> XeLaTeX*2**

The issue is about adding bilingual captions for figures and tables in a LaTeX thesis template. The user tried the bicaption package with ctexart but the template uses book class. Look at the template's document class and caption setup. Check how captions are currently defined and see if bicaption can be integrated with the book class. Test compiling with XeLaTeX to verify the solution works.
