\expandafter\expandafter\expandafter\a\expandafter\b\c Let's write it as \ex1\ex2\ex3\a\ex4\b\c.

The steps are

1. When \ex1 is executed, it saves \ex2 and expands \ex3.
   
2. When \ex3 is expanded, ti saves \a and expands \ex4. The list of saved items now consits of \ex2, \a.
   
3. When \ex4 is expanded, it saves \b and expands \c. Thus \c is the first of \a, \b, and \c to be expanded.
   
4. The list of saved items (\ex2\a\b) is placed in front of the expansion of \c, and TeX continues normal processing. However, the first otken that it sees is \ex2. It therefore saves \a, expands \b, and finally expands \a.

This example reverses the normal expansion of tokens \a, \b, and \c.

An application: \expandafter\expandafter\expandafter\lowercase\expandafter{\jobname}.

Due to its intrinsic inflexibilities, I'm thinking about either abandoning LaTeX entirely or at least designing new class files to suit my taste. I'm planning three months' time to learn about basic Java programming so as to be able to program with greater ease in TeX.
The short-time goal will be to switch TeX (the plain format) or to design new class files.

Meanwhile, I'll be trying out ConTeXt. If it proves as flexible as is described, I'll be switching to ConTeXt.

The whole pace should be faster (actually much faster) then described above.

Both packages are quite easy to install. Just drag the source files to \texmf\tex\latex and everything's set.

1. Install TeX using I-installer.
   1) Download ll2.dmg at http://ii2.sourceforge.net.
   2) Drag i-installer to /Applicaton/utilities.
   3) Launch i-installer, choose i-package --> Known Package i-Directory.
   4) Install the following (order!)
       * FreeType 2
       * libwmf
       * Ghostscript 8
       * ImageMagick
       * FrontForge
       * TeX
2. Install TeXshop
   1) Download TeXshop at http://www.uoregon.edu/~koch/texshop/obtaining.html
   2) Drag it into the Application folder.
   3) In Preferences --> encoding, choose "mac Chinese Simplified."
   
3. Set up Chinese
   1) The first solution is to use XeTeX.
       * Launch I-installer again.
       * Choose jonathan Kew's i-Directory @ SIL in i-directories.
       * Install "TeX support: XeTeX."
       * Test file:
         \documentclas{article}
         \usepackage{fontspec}
         \setromanfont{Apple LiSung Light}
         \begin{document}
         你好
         \end{document}
        * Compile it with XeLaTeX.
   2) The better solution is to use the CJK package.
   Download the CJK package from http://cjk.ffii.org/. Uncompress it and put the output at /usr/local/teTeX/share/texmf.local/tex/latex/CJK.
   Then you have to set up the fonts, which is quite troublesome. The easiest way is to copy the localtexmf folder of CTeX to /usr/local/teTeX/share/texmf.local. Then go to texmf.local/pdftex/config, make a copy of psfonts.map and rename it to pdftex.map. In terminal, execute the command "sudo mktexlsr" and it should work.
