I made some mistakes before.

>From source here:
https://code.google.com/p/ctex-kit/source/browse/#svn%2Ftrunk%2Fctex%2Ftest
and pdf file here:
http://ustcscgy.github.io/files/test-cjk.pdf
Page 21, shows and compares Chinese fonts and English fonts in Family
{rm,sf,tt},
Series {normal,bf}, Shape {normal,it,sl}.

and in font definition file from
https://code.google.com/p/ctex-kit/source/browse/trunk/ctex/fontset/ctex-fontset-fandol.def

  
\setCJKmainfont[BoldFont=FandolSong-Bold,ItalicFont=FandolKai]{FandolSong-Regular}
  \setCJKsansfont[BoldFont=FandolHei-Bold]{FandolHei-Regular}
  \setCJKmonofont{FandolFang}
  \setCJKfamilyfont{zhsong}[BoldFont=FandolSong-Bold]{FandolSong}
  \setCJKfamilyfont{zhhei} [BoldFont=FandolHei-Bold]{FandolHei}
  \setCJKfamilyfont{zhfs}  {FandolFang}
  \setCJKfamilyfont{zhkai} {FandolKai}

So, FandolKai for italic, FandolSong-Bold for bold, no such "small caps"
concept in Chinese, FandolHei-Regular for sans serif, FandolFang for
monospaced typewriter(differences between typewriter and monospaced?)

1. Chinese and Taiwanese have different custom in punctuation
typesetting, Chinese punctuations are low while Taiwanese punctuations
are in the middle.
2. As a result, different fonts have different locations for
punctuation symbols.
3. Even in Chinese case, there are a few styles: "quanjiao"(full width),
"banjiao"(half width), "hangmobanjiao"(half width in the end of line),
"kaiming"(half width except full stop symbols, most widly used).
Here is the example provided by LaTeX package CJKpunct:
http://ustcscgy.github.io/files/CJKpunct-example.pdf

In LaTeX package ctex, they provide default CJKpunct settings for default
fonts, and users have to provide their own settings for others fonts in order
to get high quality typesetting.

Normal US layout keyboard, these symbols are input by fcitx software.
The symbols are left double quote 201C, right double quote 201D,
Chinese dash 2014
(used and inputed by pair), Chinese ellipsis 2026(used and inputed by
pair), TeXmacs
gives:
