Use of Chinese numers similar to \Roman and \Arabic

Question

When formatting sections, I see things like \renewcommand \thesection{\Roman{section}}.

I'm currently working on a set of Japanese History course notes, how would one go about defining a \Chinese command to use chinese/japanese numbering for my chapter headings?

Alternatively, if someone could point me to the place in the LaTeX codebase where I could find the particular definition that would work as well. I attempted to grep and find in my texlive installation but failed to find it.

There is the zhnumber package. The documentation might tell you more than me …

\documentclass{article}
\usepackage{xeCJK}
\setCJKmainfont{SimSun}
\usepackage{zhnumber}
\renewcommand\thesection{\zhnum{section}}
\renewcommand{\thesubsection}{\thesection.\zhnum{subsection}}
\begin{document}
\section{One}
\setcounter{section}{9}
\section{Ten}
\subsection{Ten.One}
\setcounter{section}{74}
\section{Seventy four}
\setcounter{section}{999}
\section{One thousand}
\end{document}

Output
