Preparing Chinese in LaTeX

\usepackage{CJKutf8}

\begin{CJK}{UTF8}{bsmi}
中文
\input{ChinesePage}
\end{CJK}

You may need a UTF8 text editor to edit Chinese. LEd cannot do it, but you may use other text editor (e.g., notepad++) to edit Chinese, and then use \input{} to include the words.
Use gbsn instead of bsmi for simplified Chinese.
