How to typeset i-Ching Trigram and Hexagram Symbols
% XeLaTeX can use any Mac OS X font. See the setromanfont command below.
% Input to XeLaTeX is full Unicode, so Unicode characters can be typed directly into the source.
% The next lines tell TeXShop to typeset with xelatex, and to open and save the source with Unicode encoding.
%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode

\usepackage{geometry} % See geometry.pdf to learn the layout options. There are lots.

% Will Robertson's fontspec.sty can be used to simplify font choices.
% To experiment, open /Applications/Font Book to examine the fonts provided on Mac OS X,
% and change "Hoefler Text" to any of these choices.

% For many users, the previous commands will be enough.
% If you want to directly input Unicode, add an Input Menu or Keyboard to the menu bar
% using the International Panel in System Preferences.
% Unicode must be typeset using a font containing the appropriate characters.
% Remove the comment signs below for examples.

The I Ching, also known as the Book of Changes, Classic of Changes contains a divination system which includes 8 trigrams and 64 Hexagrams.
It might be obvious for TeXnician, not to mention TeXperts, but as for a newbie, its quite a struggle to figure out how to typeset these Chinese i-Ching (Yì Jīng {\C 易经}) divination symbols.
In this article, I assume you are using TeX Live on Mac OS X, because we need a special font Apple Symbols,
{\iching ☰☱☲☳☴☵☶☷}
In TeXShop, Edit -> Special Characters -> Divination Symbols. Double click the symbol to insert into your text.
