I am using xelatex and want to use the xeCJK package, but without indenting the first paragraph of a section. I tried the setup directive below, which should do the trick. But it does not. The manual is in Chinese ...

\documentclass{article}


\usepackage{xeCJK}
\setCJKmainfont{SimSun}
\xeCJKsetup{indentfirst=false}


\begin{document}

\section{Section 1}

I want to have a paragrpah without indentation.

This one should be indented.

\subsection{Section 2}

Same here.

This one should be indented.


\end{document} 



Question: Is the following usage of "matter-of-factly" correct?
Answer: The issue with the second usage is that "matter-of-factly" means "in a matter-of-fact style"; it is not synonymous with "as a matter of fact".  "As a matter of fact" is by itself already an adverbial phrase (meaning "actually"); tacking an additional -ly on the end to re-adverbialize it can't be right.

I'd be more inclined to express your friends' apparent intended meaning as "I don't know personally" or "I don't know directly".
