I am trying to use some Chinese characters in my Latex document(But it is not entirely in Chinese) and this is the website that I came across. According to the author, all I need is to use ctex package, but when I copy paste the example code in his website it failed to compile with the error message critical package ctex error:ctex fontset"fandol" is unavailable in current I wonder what went wrong? And if his method is incorrect, I wonder if there is another way that allow me to type Chinese successfuly. (I can not change the documentclass as I am trying to use a poster theme template and the documentclass ,I assume, is predefined.)
MWE:
\documentclass[UTF8]{ctexart}
\usepackage[T1]{fontenc}
\begin{document}
你好,这是一个测试文档。
\end{document}
edit: include the error message and picture
edit2: uploaded the wrong one. inlcude the correct picture[!
