+of the document @emph{Proposal for Offering TeX Courses and Relevant Resources
+in Chongqing University}.  This proposal could be helpful if one is
+considering to suggest their (Chinese) university or company to use TeX (or
+LaTeX, or XeLaTeX} as a typesetting system.
+
+The present proposal mainly explains the importance and necessity of
+introducing TeX, a typesetting system often used in academic writing, to
+students and teachers.  This proposal starts from a brief introduction of TeX,
+then steps further into its fascinating application to academic writing and
+dissertation formatting.  Finally, a set of possible implementation strategies
+with regard to the proper introduction of TeX and relevant resources to our
+university, is proposed.")
