I'm just a casual user of xecjk, but in xeCJK.dtx
you can see the following code:

    % \pkg{xeCJK} 必须使用 \XeTeX 引擎的支持。
    %    \begin{macrocode}
    \msg_new:nnn { xeCJK } { Require-XeTeX }
        You~must~change~your~typesetting~engine~to~"xelatex" \\

This means it still requires XeTeX to work.

I see.

        Thanks, Akira
