\section{Introduction}

\cls{fduthesis} is a thesis template for Fudan University.
This template is mostly written in \LaTeX3 syntax, and
provides a simple interface for users.

\subsection*{Getting started with \LaTeX{}}

This documentation is \emph{not} a \LaTeX{} tutorial at
starter's level. If you are totally a newbie, please read some
introductions like the famous \pkg{lshort}. Of course, there
are countless \LaTeX{} tutorials on the Internet. You can
choose whatever you like.

\subsection*{About this documentation}

In this documentation, different typefaces are used to
represent different contents. Packages and classes are shown
in sans-serif font, e.g.\ \pkg{xeCJK} package and
\cls{fduthesis} class. Commands and file names are shown in
monospaced font, e.g.\ command \cs{fdusetup}, environment
\env{abstract} and \TeX{} document \file{thesis.tex}.
Italic-shaped font with angle brackets outside means arguments,
e.g.\ \meta{English title}. However, you do not need to type
the brackets when using these commands. The example code has
proper syntax highlighting so it will be much easier to read.

\LaTeX{} code lines will have a blue line on their left, while
for command lines there will be a pink line. The options,
commands and environments in \cls{fduthesis} will be surrounded
by two horizontal lines. Their usages and descriptions are
provided at the same time.

The options, commands and environments in \cls{fduthesis} can be
divided into the following three types:
\begin{itemize}
  \item Those can be only used in \emph{Chinese templates} are
    indicated by \rexptarget\rexpstar{}.
  \item Those can be only used in \emph{English templates} are
    indicated by \rexptarget\expstar{}.
  \item If they do not have marks afterwards, then you can use
    them in both Chinese and English templates.
\end{itemize}

\section{Installation}

\subsection{Obtaining \cls{fduthesis}}

\subsubsection{Standard installation}

If there are no special reasons, it is always recommended to
install \cls{fduthesis} with a package manager. For example,
the following command will install the package in \TeXLive{}
(administrator permission may be required):
\begin{shellexample}[gobble=1,morekeywords={tlmgr,install}]
  tlmgr install fduthesis
\end{shellexample}

In \TeXLive{} and \MiKTeX{}, you can also install \cls{fduthesis}
through a graphical interface. It's rather simple and will not be
described here.

\subsubsection{Install manually}

If you want to download the template from CTAN and install it
manually, the recommended way is to use the TDS ZIP file:
\begin{itemize}
  \item Download the \href{http://mirror.ctan.org/install/macros/latex/contrib/fduthesis.tds.zip}%
    {TDS ZIP file} for \cls{fduthesis};
  \item Copy all the files in \file{fduthesis.tds.zip} into the
    local TDS directory of \TeX{} distribution.
  \item Run \texttt{mktexlsr} to update the ls-R database.
\end{itemize}
\subsubsection{Development version}

On CTAN, only the stable version of \cls{fduthesis} is provided, where new features and
bug fixes may not be included in time. To use the latest development version on GitHub,
you can use the install script:
\begin{itemize}
  \item Open the project's \href{https://github.com/stone-zeng/fduthesis}{homepage}, click
    ``Code'' button and choose ``Download ZIP'' to download \file{fduthesis-main.zip}.
    If you have git program on your computer, you can also clone the repository directly:
    \begin{shellexample}[gobble=5,alsoletter={.},morekeywords={git,clone}]
      git clone https://github.com/stone-zeng/fduthesis.git
    \end{shellexample}
  \item Run \file{install-win.bat} (Windows) or \file{install-unix.sh} (Linux or macOS),
    all the necessary files will be found in the \file{thesis} folder then.
\end{itemize}

\subsubsection{Overleaf}

\cls{fduthesis} also provides the \href{https://www.overleaf.com/latex/templates/fduthesis-latex-thesis-template-for-fudan-university/svtdhhstkmkt}{Overleaf version}.
You can follow the link and login to edit directly on the web.

\subsection{Composition of the template}

There are several parts in \cls{fduthesis}, including kernel template
classes, configuration files, affiliated packages and user's guides.
More details are listed in table~\ref{tab:fduthesis-components}.

\begin{table}[ht]

\section{User's guide}

\subsection{Getting started}

Here is a minimal \TeX{} file for \cls{fduthesis}:
\begin{latexexample}[gobble=1,deletetexcs={\documentclass},
    moretexcs={\chapter},morekeywords={\documentclass},
    emph={[2]document}]
  % thesis.tex
  \documentclass{fduthesis}
  \begin{document}
    \chapter{欢迎}
    \section{Welcome to fduthesis!}
    你好，\LaTeX{}！
  \end{document}
\end{latexexample}

Compile this file under the instructions in
subsection~\ref{subsec:compilation}, you will get a 5-page article.
Of course, most of it will be blank, as you may predicate.

The English version can be used in the same way:
\begin{latexexample}[gobble=1,deletetexcs={\documentclass},
    moretexcs={\chapter},morekeywords={\documentclass},
    emph={[2]document}]
  % thesis-en.tex
  \documentclass{fduthesis-en}
  \begin{document}
    \chapter{Welcome}
    \section{Welcome to fduthesis!}
    Hello, \LaTeX{}!
  \end{document}
\end{latexexample}
The differences between English and Chinese version only
live in the main body. Thesis cover, instructors list and
declaration page are still printed in Chinese.

\subsection{Compilation} \label{subsec:compilation}

\cls{fduthesis} does NOT support \pdfTeX{}. Please use
\XeLaTeX{} or \LuaLaTeX{} to compile, and \XeLaTeX{} is
recommended. To get the correct table of contents, footnotes
and cross-references, you need to compile the source file at
least twice.

In the following example, suppose your \TeX{} source file is
\file{thesis.tex}. Please execute the following commands if
you want to use \XeLaTeX{}:
\begin{shellexample}[gobble=1,morekeywords={xelatex}]
  xelatex thesis
  xelatex thesis
\end{shellexample}
You can use \pkg{latexmk} as well:
\begin{shellexample}[gobble=1,morekeywords={latexmk},emph={-xelatex}]
  latexmk -xelatex thesis
\end{shellexample}

\LuaLaTeX{} can be used in a similar way:
\begin{shellexample}[gobble=1,morekeywords={lualatex}]
  lualatex thesis
  lualatex thesis
\end{shellexample}
or
\begin{shellexample}[gobble=1,morekeywords={latexmk},emph={-lualatex}]
  latexmk -lualatex thesis
\end{shellexample}

\subsection{Options of the template}

You can specify some \emph{template options} when loading
\cls{fduthesis}:
\begin{latexexample}[gobble=1,deletetexcs={\documentclass},
    morekeywords={\documentclass}]
  \documentclass(*\oarg{options}*){fduthesis}
  \documentclass(*\oarg{options}*){fduthesis-en}
\end{latexexample}

Some options are \emph{boolean} --- they only take the value
\opt{true} or \opt{false}. For these options, you can
abbreviate ``\kvopt{\meta{option}}{true}'' simply to
``\opt{\meta{option}}''.

\begin{function}[added=2018-02-01]{type}
  \begin{fdusyntax}[gobble=4,emph={[1]type}]
    type = (*<doctor|master|(bachelor)>*)
  \end{fdusyntax}
  Choose the type of your thesis. The three options represent
  doctoral dissertation, master degree thesis and undergraduate
  thesis, respectively.
\end{function}

\begin{function}{oneside,twoside}
  Specify whether single or double sided output should be
  generated. \opt{twoside} will be chosen by default. These
  option will determine where the new chapters begin and how
  the headers display. The option \opt{twoside} does
  \emph{not} tell the printer to actually make a two-sided
  printout.
\end{function}

If choosing \opt{twoside}, chapters will begin at the odd pages
(right hand). However, they will begin at arbitrary pages
available when choosing \opt{oneside}. Table of contents,
abstract and the list of symbols are considered as chapters and
processed in the same way.

At two-sided mode, left headers on the even pages (left hand)
in \emph{main body} will show the title of chapters, while the
right headers on the odd pages (right hand) will show the
title of sections. Headers in \emph{front matter} have the
same style, but they will only show the title as ``Contents'',
``Abstract'', etc.

At one-sided mode, both left and right headers on \emph{all}
pages in main body will be shown. The text is the title of
chapters and sections, respectively. In front matter, there
are only middle headers, which show the corresponding titles.

\begin{function}{draft}
  \begin{fdusyntax}[gobble=4,emph={[1]draft}]
    draft = (*<\TFF>*)
  \end{fdusyntax}
  Enable draft mode. Default off.
\end{function}

\opt{draft} is a global option and will affect many packages.
You may notice the following changes when using \opt{draft}:
\begin{itemize}
  \item Lines with overfull \tn{hbox}'s will be marked with
    a thick black square on the right margin.
  \item Will not include graphics files actually, but instead
    print a box of the size the graphic would take up, as well
    as the file name.
  \item Will not make hyperlinks and PDF bookmarks.
  \item Show the page frames.
\end{itemize}

\begin{function}[added=2018-01-31]{config}
  \begin{fdusyntax}[gobble=4,emph={[1]config}]
    config = (*\marg{file}*)
  \end{fdusyntax}
  File name of user profile. Default value is empty, so no
  profile is loaded automatically.
\end{function}

\subsection{More options}

\begin{function}{\fdusetup}
  \begin{fdusyntax}[gobble=4,morekeywords={\fdusetup}]
    \fdusetup(*\marg{key-value list}*)
  \end{fdusyntax}
  \cls{fduthesis} has provided a number of options, which
  can be given via the general command \cs{fdusetup}.
\end{function}

The argument of \cs{fdusetup} is a set of comma-separated option list.
The options usually have the form of \kvopt{\meta{key}}{\meta{value}}
and in some cases \meta{value} can be omitted.
For the same option, the values given later will override the
the previous ones. Default values are indicated in
\textbf{boldface} in the following descriptions.

\cs{fdusetup} follows \LaTeX3 key-value style, and different
types as well as various levels options are supported. In the
key-value list, spaces around ``|=|'' will be trimmed; however,
blank lines should never appear in the argument.

Similar with template options, ``\kvopt{\meta{option}}{true}''
can be abbreviated to \opt{\meta{option}} for boolean type.

Some options, such as \opt{style} and \opt{info}, may have
sub-options. They can be set by the following two equivalent
methods:
\begin{latexexample}[gobble=1,morekeywords={\fdusetup},
    emph={[1]style,cjk-font,font-size,info,title,title*,author,author*,department}]
  \fdusetup{
    style = {cjk-font = adobe, font-size = -4},
    info  = {
      title      = {论动体的电动力学},
      title*     = {On the Electrodynamics of Moving Bodies},
      author     = {阿尔伯特·爱因斯坦},
      author*    = {Albert Einstein},
      department = {物理学系}
    }
  }
\end{latexexample}
or
\begin{latexexample}[gobble=1,morekeywords={\fdusetup},
    emph={[1]style,cjk-font,font-size,info,title,title*,author,author*,department}]
  \fdusetup{
    style/cjk-font  = adobe,
    style/font-size = -4,
    info/title      = {论动体的电动力学},
    info/title*     = {On the Electrodynamics of Moving Bodies},
    info/author     = {阿尔伯特·爱因斯坦},
    info/author*    = {Albert Einstein},
    info/department = {物理学系}
  }
\end{latexexample}

Note that you may \emph{not} put spaces around ``|/|''.

\subsubsection{Style and format} \label{subsubsec:style-and-format}

\begin{function}{style}
  \begin{fdusyntax}[gobble=4,emph={[1]style}]
    style = (*\marg{key-value list}*)
    style/(*\meta{key}*) = (*\meta{value}*)
  \end{fdusyntax}
  This general option is for setting the thesis style and format.
  See the following details.
\end{function}

\begin{function}[updated=2019-03-05]{style/font}
  \begin{fdusyntax}[gobble=4,emph={[1]font}]
    font = (*<garamond|libertinus|lm|palatino|(times)|times*|none>*)
  \end{fdusyntax}
  Set fonts (including math fonts). The details can be found in table~\ref{tab:font}.
\end{function}

\begin{table}[ht]
\begin{threeparttable}
  \caption{Font configuration}
  \label{tab:font}

    \item[b] ``TG'' is the abbreviation of TeX Gyre.
    \item[c] Here, Times New Roman, Arial and Courier New are commercial fonts. They are
      installed on Windows and macOS by default.
  \end{tablenotes}
\end{threeparttable}
\end{table}
\begin{function}[rEXP,updated=2019-03-05]{style/cjk-font}
  \begin{fdusyntax}[gobble=4,emph={[1]cjk-font}]
    cjk-font = (*<adobe|(fandol)|founder|mac|sinotype|sourcehan|windows|none>*)
  \end{fdusyntax}
  Set CJK (Chinese, Japanese and Korean) fonts. The details can be found in
  table~\ref{tab:cjk-font}.
\end{function}

\begin{table}[ht]
  \caption{CJK font configuration}
  \label{tab:cjk-font}

    \bottomrule
  \end{tabular}
\end{table}

When you choose \kvopt{font}{none} or \kvopt{cjk-font}{none},
\cls{fduthesis} will disable the default western/CJK font
settings. You may use \cs{setmainfont}, \cs{setCJKmainfont}
and \cs{set\-math\-font}, etc.\ to configure the fonts manually.

\begin{function}{style/font-size}
  \begin{fdusyntax}[gobble=4,emph={[1]font-size}]
    font-size = (*<(-4)|5>*)
  \end{fdusyntax}
  Specify the basic font size in your thesis.
\end{function}

\begin{function}[rEXP,updated=2017-10-14]{style/fullwidth-stop}
  \begin{fdusyntax}[gobble=4,emph={[1]fullwidth-stop}]
    fullwidth-stop = (*<catcode|mapping|(false)>*)
  \end{fdusyntax}
  Let full-width full stop ``\FSFW'' as the default full stop.
  Generally, this punctuation is used for scientific articles,
  where ``\FSID'' is easily to be confused with subscript
  ``$_o$'' or ``$_0$''.
\end{function}

If you choose \kvopt{fullwidth-stop}{catcode}, only
\emph{explicit} ``\FSID'' will be replaced by ``\FSFW''; when
choosing \kvopt{fullwidth-stop}{mapping}, however, \emph{all}
the ``\FSID'' will be replaced.

\opt{mapping} is valid only under \XeTeX{}. When compiling
with \LuaTeX{}, it is equivalent to \opt{catcode}.

If you want to display ``\FSID'' temporarily after setting
\kvopt{fullwidth-stop}{mapping}, the following code snippet
will be helpful:
\begin{latexexample}[gobble=1,moretexcs={\CJKfontspec},emph={[1]Mapping}]
  % Compiled with XeTeX
  % The outside braces is used for group
  这是一个句号{\CJKfontspec{(*\meta{font name}*)}[Mapping=full-stop]。}
\end{latexexample}

\begin{function}{style/footnote-style}
  \begin{fdusyntax}[gobble=4,emph={[1]footnote-style}]
    footnote-style = (*<plain|\\
      ....\mbox{}~~~~~~~~~~~~~~~~~libertinus|libertinus*|libertinus-sans|\\
      ....\mbox{}~~~~~~~~~~~~~~~~~pifont|pifont*|pifont-sans|pifont-sans*|\\
      ....\mbox{}~~~~~~~~~~~~~~~~~xits|xits-sans|xits-sans*>*)
  \end{fdusyntax}
  Set the style of footnote numbers. Note that western fonts
  will affect its default value (see table~\ref{tab:footnote-font}),
  so you may put it after |font| option. The one with |sans|
  is for the corresponding sans-serif version, while |*|
  for white on black version.
\end{function}

\begin{table}[ht]

\subsection{Writing your thesis}

\subsubsection{Front matter}

\begin{function}{\frontmatter}
  Declare the beginning of front matter.
\end{function}

Front matter contains table of contents, abstracts and notation
list. The page numbers in front matter will be shown in
lowercase Roman numerals, and will be counted separately with
main matter.

\begin{function}{\tableofcontents}
  Generate the table of contents (TOC). You need to compile
  the source file at least \emph{twice} to get the correct TOC.
  If your thesis contains many figures or tables, you may also
  use \cs{listoffigures} or \cs{listoftables} to generate a list
  of them.
\end{function}

\begin{function}{abstract}
  \begin{fdusyntax}[gobble=4,emph={[2]abstract}]
    % fduthesis (Chinese thesis)    % fduthesis-en (English thesis)
    \begin{abstract}                \begin{abstract}
      (*\meta{Chinese abstract} \hspace{3cm} \meta{English abstract}*)
    \end{abstract}                  \end{abstract}
  \end{fdusyntax}
\end{function}
\begin{function}[rEXP]{abstract*}
  \begin{fdusyntax}[gobble=4,emph={[2]abstract*}]
    % Only for fduthesis
    \begin{abstract*}
      (*\meta{English abstract}*)
    \end{abstract*}
  \end{fdusyntax}
  Abstract environment. In \cls{fduthesis}, \env{abstract} and
  \env{abstract*} are used for Chinese and English abstract,
  respectively; while in \cls{fduthesis-en}, there is no
  \env{abstract*} environment and you need to write the English
  abstract merely.
\end{function}

At the end of abstract (both Chinese and English, if available),
keywords list and CLC or JEL code will be shown. They can be
specified via command \cs{fdusetup} and you may refer to
subsubsection~\ref{subsubsec:information} for more details.

\begin{function}{notation}
  \begin{fdusyntax}[gobble=4,emph={[2]notation}]
    \begin{notation}(*\oarg{column format}*)
      (*\meta{symbol 1}*)  &  (*\meta{description}*)  \\
      (*\meta{symbol 2}*)  &  (*\meta{description}*)  \\
      (*\phantom{\meta{symbol $n$}}*)  (*$\vdots$*)
      (*\meta{symbol \kern-0.1em$n$}*)  &  (*\meta{description}*)
    \end{notation}
  \end{fdusyntax}
  Notation list (or symbol list, nomenclature) environment.
  The optional argument \meta{column format} is the same as
  in a standard \LaTeX{} table. The default value is
  ``|lp{7.5cm}|'', which means auto-width for the first column
  and fix-width (\qty{7.5}{cm}) for the second; both columns will
  be left-aligned.
\end{function}

\subsubsection{Main matter}

\begin{function}{\mainmatter}
  Declare the beginning of main matter.
\end{function}

As the name suggests, ``main matter'' is the main body of your
thesis. When working on a big projects, it's usually a good
idea to split the source file into several parts. The page
numbers in main matter are shown in arabic numerals.

\begin{function}[updated=2018-01-15]{\footnote}
  \begin{fdusyntax}[gobble=4,deletetexcs={\footnote},morekeywords={\footnote}]
    \footnote(*\marg{text}*)
  \end{fdusyntax}
  Insert a footnote. The style of footnote numbers can be set
  with option \opt{style/foot\-note\-style}. See
  subsubsection~\ref{subsubsec:style-and-format} for more details.
\end{function}

\begin{function}{\caption}
  \begin{fdusyntax}[gobble=4,deletetexcs={\caption},morekeywords={\caption}]
    \caption(*\marg{caption}*)
    \caption(*\oarg{short caption}\marg{long caption}*)
  \end{fdusyntax}
  Insert the caption of figure or table. The optional argument
  \meta{short caption} will be shown in the list of figures/tables.
  In \meta{long caption}, you can write descriptions for several
  paragraphs, but \meta{short caption} and the single
  \meta{caption} will not allow multi-paragraph text (i.e.\
  text containing \tn{par}) inside.
\end{function}

By convention, caption of a table is usually put \emph{before}
the table itself, while for figure it's the opposite.
In addition, command \tn{caption} must be put inside float
environments (e.g.\ \env{table} and \env{figure}).

\paragraph{Citations}
\begin{function}[updated=2021-09-20]{\cite}
  \begin{fdusyntax}[gobble=4,deletetexcs={\cite},morekeywords={\cite}]
    \cite(*\marg{bib key}*)
    \cite(*\oarg{page number}\marg{bib key}*)
  \end{fdusyntax}
  Insert citations. The optional argument \meta{page number} can be
  used to indicate the page number of the citation. The citation style
  varies among different bibliography styles. More commands are also
  provided to mark the citations, which can be found in
  table~\ref{tab:citation-numerical} (numerical style) and
  \ref{tab:citation-author-year} (author-year style).
\end{function}

\paragraph{Theorem-like environments}
\begin{function}{axiom,corollary,definition,example,lemma,
  proof,theorem}
  \begin{fdusyntax}[gobble=4,emph={[2]proof}]
    \begin{proof}(*\oarg{subheading}*)
      (*\meta{procedure of proof}*)
    \end{proof}
  \end{fdusyntax}
  A series of pre-defined math environments.
\end{function}

A QED\footnote{Abbreviation of Latin phrase \emph{quod erat
  demonstrandum}, means ``what was to be demonstrated''.}
symbol ``$\QED$'' will be added at the end of \env{proof}
environment. You need to compile the source file \emph{twice}
as in subsection~\ref{subsec:compilation} in order to make
the position of QED symbol correct.

\begin{function}[updated=2017-12-12]{\newtheorem}
  \begin{fdusyntax}[gobble=4,deletetexcs={\newtheorem},
      morekeywords={\newtheorem,\newtheorem*}]
    \newtheorem(*\oarg{options}\marg{environment}\marg{title}*)
    \newtheorem*(*\oarg{options}\marg{environment}\marg{title}*)
    \begin(*\marg{environment}\oarg{subheading}*)
      (*\meta{contents}*)
    \end(*\marg{environment}*)
  \end{fdusyntax}
  Declare new math environments (theorems). If you use
  \cs{newtheorem*}, then the theorem will not be numbered, and
  a QED symbol ``$\QED$'' will be added at the end of the
  environment. All the theorem environments defined by yourself
  can be used as the pre-defined ones.
\end{function}

Actually, the pre-defined math environments are just defined
with \cs{new\-the\-o\-rem} and \cs{new\-the\-o\-rem*}:
\begin{latexexample}[gobble=1,deletetexcs={\newtheorem},
    morekeywords={\newtheorem,\newtheorem*}]
  \newtheorem*{proof}{proof}
  \newtheorem{axiom}{axiom}
  \newtheorem{corollary}{corollary}
  ...
\end{latexexample}

Similar with \cs{fdusetup}, the optional argument \meta{options}
of \cs{newtheorem} is a key-value list as well. The available
are described below. Note that you don't need to type in the
``|theorem/|'' prefix.

\begin{function}{theorem/style}
  \begin{fdusyntax}[gobble=4,emph={[1]style}]
    style = (*<(plain)|margin|change|\\
      XXXX\mbox{}~~~~~~~~break|marginbreak|changebreak>*)
  \end{fdusyntax}
  The overall style of the theorem environment.
\end{function}

\begin{function}{theorem/header-font}
  \begin{fdusyntax}[gobble=4,emph={[1]header-font}]
    header-font = (*\marg{font}*)
  \end{fdusyntax}
  Font of the theorem header. Default value is \tn{sffamily}
  and |\bfseries\upshape| for Chinese and English template,
  respectively.
\end{function}

\begin{function}{theorem/body-font}
  \begin{fdusyntax}[gobble=4,emph={[1]body-font}]
    body-font = (*\marg{font}*)
  \end{fdusyntax}
  Font of the theorem body. Default value is \tn{fdu@kai}
  (\textit{楷体}) and \tn{itshape} for Chinese and English
  template, respectively.
\end{function}

\begin{function}{theorem/qed}
  \begin{fdusyntax}[gobble=4,emph={[1]qed}]
    qed = (*\marg{symbol}*)
  \end{fdusyntax}
  Theorem end mark. For \cs{newtheorem}, default value is
  empty; for \cs{newtheorem*}, default value is
  |\ensuremath{\QED}| (i.e.\ ``$\QED$'').
\end{function}

\begin{function}{theorem/counter}
  \begin{fdusyntax}[gobble=4,emph={[1]counter}]
    counter = (*\marg{counter}*)
  \end{fdusyntax}
  The theorem will be enumerated within \meta{counter}. For
  example, the default value is |chapter|, which means with
  each new \tn{chapter}, the enumeration begins again with 1.
  This option is invalid for \cs{newtheorem*}.
\end{function}

\subsubsection{Back matter}

\begin{function}{\backmatter}
  Declare the beginning of back matter.
\end{function}

Back matter contains bibliography, declaration page, etc.

\begin{function}[updated=2018-01-25]{\printbibliography}
  \begin{fdusyntax}[gobble=4,morekeywords={\printbibliography}]
    \printbibliography(*\oarg{options}*)
  \end{fdusyntax}
  Print the bibliography. When \kvopt{bib-backend}{bibtex}, then
  \meta{options} is invalid and this command is equivalent to
  \tn{bibliography} \texttt{\marg{bib files}}, where \meta{bib files}
  should be specified with option \opt{style/bib-resource} (see

\section{Packages dependencies}

Different compilation methods and options will result in a
different packages dependency. Details are as follows:
\begin{itemize}
  \item In any case, \cls{fduthesis} will load the following
    packages \emph{explicitly}:
    \begin{itemize}
      \item \pkg{xtemplate} and \pkg{l3keys2e}, belong to
        \pkg{l3packages} bundle
      \item \cls{ctexbook}, belongs to \CTeX{} bundle
      \item \pkg{amsmath}, belongs to \AmSLaTeX{} bundle
      \item \pkg{unicode-math}
      \item \pkg{geometry}
      \item \pkg{fancyhdr}
      \item \pkg{footmisc}
      \item \pkg{ntheorem}
      \item \pkg{graphicx}
      \item \pkg{longtable}
      \item \pkg{caption}
      \item \pkg{xcolor}
      \item \pkg{hyperref}
    \end{itemize}
  \item When chosen \kvopt{style/footnote-style}{pifont},
    package \pkg{pifont} will be loaded. It belongs to
    \pkg{psnfss} bundle.
  \item When chosen \kvopt{style/bib-backend}{bibtex},
    package \pkg{natbib} will be loaded. Meanwhile, program
    \BibTeX{} will be required for compilation. The
    bibliography style is provided by \pkg{gbt7714}.
  \item When chosen \kvopt{style/bib-backend}{biblatex},
    package \pkg{biblatex} will be loaded. Program \biber{}
    will be required then. The bibliography style is provided
    by \pkg{biblatex-gb7714-2015}.
\end{itemize}

Only the packages loaded directly by \cls{fduthesis} are listed
here. If you need to know the dependencies of the packages
themselves, please refer to the corresponding manuals.
