我创建了一个 cls 文件，以便制作我自己的文档样式。一切都运行良好，但是，当我有一些代码以便用不同的语言编写时（参见 cls 文件），它就不再起作用了。您有什么想法吗？
这是一个基本的例子：
\documentclass{Internship_Report}
\usepackage{multirow}
\usepackage{longtable}
\usepackage{lscape}
\usepackage{makecell}
\usepackage{tabularx}
\usepackage{color}
\usepackage{xcolor}
\usepackage{colortbl}
\usepackage{fancyhdr}
\usepackage{enumitem}
\usepackage[breaklinks,hidelinks]{hyperref}
\begin{document}
\begin{center}
\huge{\bfseries{Acknowledgements}}
\vspace{0.3cm}
\end{center}
\chineseLanguage{非常感谢您} M; \<شكرًا لك أيها> ; \greekLanguage{Σας ευχαριστώ πoulos} and V
\tableofcontents
