Thank you for reply. I have already done that. But when checking out the latex source, I still see the following codes:
--- \usepackage{ccmap} \AtBeginDocument{\begin{CJK*}{GBK}{song}} \AtEndDocument{\end{CJK*}} \makeatother \begin{document} \begin{CJK}{GBK}{} Hello \end{CJK} \end{document} --- Obviously the global settings I put in Preamble were still over-ridden by the default codes of LyX. What to do? Besides, how does LyX choose font even when \begin{CJK}{GBK}{} does not specify one? regards, -- bxf
