A simple way to support Chinese in texlive

1. Make sure the encoding of the tex file is UTF-8,

2. Add a line of command at the beginning of the document, that is

\usepackage[UTF8]{ctex} ，

As follows:

\documentclass{article}
\usepackage[UTF8]{ctex}
\begin{article}
test
Chinese
\end{article}

Chinese can be displayed after compiling.
