Yet another way to use Chinese charecter in Latex

First, install texlive-lang-cjk or texlive-lang-chinese or texlive-lang-all. Then in tex file, add:

usepackage[T1]{fontenc}  
usepackage{CJKutf8}  
newenvironment{SChinese}{%
  CJKfamily{gbsn}%
  CJKtilde
  CJKnospace}{}

Whenever a Chinese character is needed, use

begin{SChinese}凡end{SChinese}
