\section{Registration and Conference Fee}
In short
\begin{itemize}
\item[(1)] you need to make a bank transfer for the conference
fee in your local currency, and
\item[(2)] you need to email Xingyuan with your details\\
(\xyzemail)
\end{itemize}
\noindent Xingyuan will then confirm that the payment has been
received. Note that if you are Chinese and need a \emph{fa
piao} to reclaim the conference fee, you need to contact
Xingyuan directly before making any money transfer.
\medskip
\noindent The early conference fee is RMB 3300, which is
approximately \pounds{}350, \$533, or \euro{}488. It must be
transferred via bank transfer and must be made in your local
currency; we cannot accept any other form of payment. The
tutorials can be registered independently from the conference.
The conference fee includes lunches during the conference. It
also covers the excursion, the conference banquet and a
welcome reception.
\begin{center}
\begin{tabular}{l@{\hspace{4mm}}l}
Early conference fee until 31.~July: & RMB 3300\\
Late conference fee from 1.~August: & RMB 3800\bigskip\\
Additional banquet dinner and excursion: & RMB 530\\
(one is included in the conference fee)\bigskip\\
Isabelle tutorial (21 -- 23 August): & RMB 250\\
Coq tutorial (27 -- 29 August): & RMB 200\\
\end{tabular}
\end{center}
\noindent The amount payable needs to be
transferred to the account:
\begin{center}
\begin{tabular}{ll}
Account holder's name:& Zhang Xingyuan\medskip\\
Beneficiary bank:& BANK OF CHINA\medskip\\
Swift Code:& BKCHCNBJ940\medskip\\
Account number:& 504066588897\medskip\\
Beneficiary bank address:& Nanjing Mei Hua Shan Zhuang\\
& Sub-branch, Nanjing, China\medskip\\
Account holder's address:& \\
& Suite 2106, Building 20,\\
& 20 Biao Ying,\\
& Qinhuai District,\\
& Nanjing, Jiangsu Province,\\
& People's Republic of China.\\
\end{tabular}
\end{center}
\noindent {\bf Please make doubly-sure that your bank
transferral contains your full name as reference (additional
information field), and is in your local currency
(e.g.~\euro, \$, \pounds)!} Otherwise we will have no idea
where the money came from, and will not be able to receive
the money on our end. Please also make sure that your transferral
covers all bank fees.\bigskip
\section{Hotel Booking}
In short, you need to send your arrival and departure
details to Chunhan
(\cwemail).\bigskip
\noindent While it is possible to book the hotel via official
online travel web-pages, the price there is higher. The
easiest is to send Chunhan your name, arrival and departure
dates and he will send you back a booking ticket from Hanyuan
hotel, which you might need for your visa application.
You can pay the hotel when you arrive using Visa or
MasterCard.
\section{Visa}
Please be aware that for travelling to China you will need a
visa, for which you have to apply {\bf beforehand}. It often takes
one or two weeks before a visa is granted. Though if you
are prepared to pay a higher application fee, then you can
shorten the delay to a few days. For the visa you
will need an invitation letter, which Chunhan will send you
(\cwemail). You need to provide him with your name, title,
DOB, work address, e-mail and paper title (if you present a paper).
He will e-mail you the invitation letter. You might also need
your hotel booking (see above) and flight details for the visa
application.
\chapter{Arrival}
Welcome in China. You made it to the destination airport.
Unless your are one of the very few foreigners who can speak
and read Chinese, potentially the most challenging part of
your journey is about to begin. Below we explain how to get to
Hanyuan Hotel in Nanjing from Nanjing Lukou Airport and from
Shanghai Pudong Airport. If you arrive from somewhere else and
need help, please let us know.
China is generally a safe country for travelling, if the usual
precautions are taken. We assume you have never been in China
before, therefore let us still start with some general points.
\begin{itemize}
\item \textbf{Weather}\hspace{3mm}
Unfortunately end of August is the time when it will be especially
hot in Nanjing (usually above 30$^{\circ}$C). Be prepared with lots of
light clothes, but do not forget a jumper, or sweater, since many
places are air-conditioned. It can also rain.
\item \textbf{Bottled Water}\hspace{3mm}
Whereas in many places it is safe to drink water from taps,
do not take chances and drink only bottled water! During the
conference we will provide bottled water. In other places you
have to buy bottles yourself. Remember, Chinese are famous for
nibbling on hot tea the whole day, even in sweltering
temperatures. There is a reason for this.
\item \textbf{Traffic}\hspace{3mm}
Do not even think of renting a car in China. Hence, while in
China, you probably will be mostly going around on foot. Be
careful though: You might come from a region where traffic rules are
organised so that pedestrians are mostly
treated with respect by all other road users, or even have an
``elevated status'' because they are considered the ``weakest''.
Traffic in China is, in contrast, organised more, shall we say,
according to a Darwinian model: Under no circumstance assume a
car (or even a bicycle or one of the noiseless electric motor bikes) will stop for you. As pedestrian, you
have to take care of everybody else. Therefore, whenever
possible cross roads at traffic lights and even if the light
shows green for you, look out for cars that pay no attention to this
fact. Also, zebra crossings do \emph{not}, I repeat, \emph{do not}
have any special meaning in
China for the road users higher up the traffic ladder
(i.e.~bicycles and above).
Even if it sounds too funny, take
our word and head this advice\ldots{}it might increase your
life-expectancy.
\item \textbf{Free Public Wifi / Mobile Phones}\hspace{3mm}
While free public wifi is nowadays pretty ubiquitous in big
cities in China (Starbucks, Costas, McDonalds are obvious
places where to find wifi), you need a working mobile phone in
order to use it. You will have to register your number when
you log in, and the wifi operator will then send you a
password token via SMS. The problem is that chances are great
your mobile phone will \emph{not} work in China. Therefore do
not assume you can check information on the Internet while
travelling.
At the hotel there will be wifi (with the super-secure
password: 123456789). But again, do not assume you can
download that last episode of the Daily Show: while bandwidth
will generally be enough for reading email, be prepared for an
uninterrupted stay in China, free from any disturbance coming
from online demands.
\item \textbf{Google etc}\hspace{3mm}There are two Great Walls in
China: one prevents you from accessing Google, for example. Use
\url{www.aol.com} or \url{www.bing.com} instead as your preferred
search engine. Also, if you care about such things, set your
status on Facebook to ``unavailable'' for the period of time
you will be in China. Ditto Twitter. If you do want to access
those services, you need to use a VPN back home.
\item \textbf{Map of Hotel / Taxis}\hspace{3mm} While more and
more young Chinese are exposed to English, you cannot
rely on anyone of the general public speaking more than a few
words. Rather, you have to always calculate with the very,
very likely scenario that nobody speaks any English at all
and all
signs round you are written in characters that do not give you the
slightest idea what they are about. This means you always
have to prepare your travelling beforehand and ask us for help
if you are unsure!
One part of \emph{every} trip preparation, including your
arrival, should be to carry with you a printed copy of the map
where the Hanyuan Hotel is located (see Fig.~\ref{hanyuan}).
When you want to go to the hotel by taxi, you need to show the map to
the driver, since telling Hanyuan Hotel will most probably not
be understood and also the driver most likely does not know
where it is located. Showing the map will also guard against
the possible situation where a taxi driver cannot actually
read the address.\footnote{You might sneer at this. But
remember: the prime age of Chinese taxi drivers appears to be
50 plus. If you can also remember, between 1966 and 1976
somebody had the ``great'' idea to be nasty to teachers
(amonst others). So the education these people were able to
receive when their were in their teens was rather rudimentary.
Given that the ability of reading Chinese characters takes
years of arduous studying, it is glaringly obvious that it is
not their fault.} Take the map always with you: it might be
your life-line for avoiding unpleasant situations. For
travelling inside Nanjing, taxis can be hailed at the
street curb.
\item \textbf{Cash / Credit Cards}\hspace{3mm}While foreign
credit cards are accepted in a number of places, including
the hotel,\footnote{Visa and Mastercard} these places are
considered ``upmarked'' in China. So if you insist on being able
to use your credit card, you will often be paying some form of
premium. Cash still rules many aspects of Chinese life
(metro ticket, taxi journey,\ldots{}) where foreign credit cards
are of no use (China has its own credit card system which is
accepted more widely, but also not everywhere). Pretty much the
only places where cash can be obtained with a foreign credit
card are ATMs in Chinese banks.\footnote{MORE INFO NEEDED}

\section{Travel from Nanjing Lukou Airport to the Hanyuan Hotel}
There are essentially three options depending on how frugal
or adventurous you want to be:
\begin{itemize}
\item The first option is to take a taxi for the whole journey
from the airport to the hotel. Follow the taxi signs at
the airport and take a yellow taxi. The journey will
cost you around 130 RMB (\euro{}19, \$21) and takes
about 45 minutes. Show the driver the map in
Fig.~\ref{hanyuan}. The taxi needs to be paid in cash.
\item A bit less expensive is going first by Metro Line S1
from the airport to Nanjing Nan Railway Station (Nanjing
South Railway Station). The metro will operate between
6:40 and 22:00. As you can see in the map shown in
Fig.~\ref{metronanjing}, Nanjing Nan will be the last
stop on Line~S1. At Nanjing Nan Railway Station you go
to the taxi stand, which means following the yellow path
in the map below. To reach the taxi stand, you need to
leave the metro via exit 2B and follow the signs for
``Taxi (Underground)''. This option takes approximately
55 minutes and costs 7 RMB for the metro ticket and
around 36 RMB for the taxi.
\begin{center}
\includegraphics[scale=0.4]{travel_guide/ggg.jpg}
\end{center}
\item If you already paid the fixed price for the metro, why
not going the whole way by metro? This is the third
option. The disadvantage is that you need to change
at Nanjing Nan Railway Station to Line 3 and at
Daxinggong to Line 2 for Xiamafang or Muxuyuan, which
are the closest stations to the Hanyuan Hotel
(see Fig.~\ref{metronanjing}). Both
stations then need a 15 minutes walk to the hotel.
This is another disadvantage of this option if you have
a heavy suitcase.
\end{itemize}
\begin{figure}[p]

\makebox[0mm]{\includegraphics[scale=1.1]{travel_guide/metromapnanjing.png}}
\end{center}
\caption{Metro map of Nanjing. Stations
Xiamafang and Muxuyuan on Line 2 are
closest to the hotel.\label{metronanjing}}
\end{figure}
\subsubsection*{Getting a Ticket for the Metro in Nanjing}
Like in all metro stations, entering the metro station at the
airport means you have to go through a brief security check
where your luggage will be X-rayed. After the check you will
see ticket machines
\begin{center}
\includegraphics[scale=0.27]{travel_guide/20150331_110412.jpg}
\hspace{4mm}
\includegraphics[scale=0.27]{travel_guide/20150331_110548.jpg}
\end{center}
\noindent which can change the language to English (in this
way you can avoid having to talk to a sales person on the
desk). You need to select the destination station (shown on
the right). Next you need to pay for the ticket in 10 RMB or 5
RMB bank notes, or 1 RMB coins. If you do not have them yet,
you will need to go to the counter near the ticket machines.
After paying the machine will issue a blue plastic coin which
is your ticket. This coin needs to be swiped when going
through the gates of the metro (shown on the right).
\begin{center}
\includegraphics[scale=0.27]{travel_guide/20150331_110738.jpg}
\hspace{4mm}
\includegraphics[scale=0.27]{travel_guide/IMG_7177.jpg}
\end{center}
\noindent At the end of your journey you will
have to return the blue coin at the exit gate. (??)
\section{Travel from Shanghai Pudong Airport}
Many of the participants will arrive at Shanghai Pudong
Airport. From there, in short, you have to get to (1) the Hong
Qiao railway station and then from there to (2) Nanjing Nan
railway station. From Nanjing Nan it is best to take a taxi,
but you can also take the metro as explained in the previous
section. Overall this will take approximately 3h of travelling
to the hotel.
\subsection*{From Shanghai Pudong Airport to Hong Qiao Train Station}
For the first leg to Hong Qiao train station there are
essentially two travel options: one recommended by locals
and being the more sensible option is to take the airport bus;
the other is by the World's only commercial Maglev train
including a change to the metro.
\begin{itemize}
\item \textbf{Option 1 by Airport bus}:
At the Pudong Airport follow the signs for Airport Bus, or Airport
Ring Bus. You have to take Line 1, which operates between 7:00
and 23:00. The bus stop where you have to wait is
\begin{center}
\includegraphics{travel_guide/image005.jpg}
\end{center}
The waiting time is around 15 minutes during peak hours, or 30
minutes at other times. The ticket costs 30 RMB (\euro{}4.25,
\$5) and can be bought on the bus. This however requires cash.
While you wait, be prepared to be harassed by taxi drivers,
who insist on driving you to Hong Qiao train station. You can
ignore them: it will cost you more, around 100 RMB; the bus is
comfortable and air-conditioned, unlike the taxi; and, like
the taxi driver, the bus driver already aims for maximum
possible speed given good road conditions.
The airport bus takes around 1h and makes only two stops at
the very end of the journey. Both stops are in near
proximity. You have to take the \emph{second} stop at Hong Qiao
Railway Station. You will be able to see the big signs of
Hong Qiao Railway Station when you approach the station. Do
not take the exit for Hong Qiao International Airport.
\item \textbf{Option 2 Maglev train / Metro}:
Of course travelling on the Maglev is pretty cool\ldots{}
reaching speeds of 415 km/h at certain(!) times of the day,
namely 9:02--10:47 and 15:02--16:47. At other times it will
travel only at mere speeds of 300 km/h, which you get in China
also with conventional high-speed trains. Anyway, a
ticket for the Maglev will set you back around 50 RMB (\euro{}7, \$8). The
ticket can be paid in cash or with credit card.
The service of the Maglev
starts at 7:02 and finished the day at 21:42.
To take this option
at the airport, you will need to follow the Maglev signs. The
main problem with
this option, however, is that you can only go until Longyang
Road Station and then have to
change into the overcrowded and much, much slower metro Line 2.
The change to the
metro is a short walk from the Maglev. You have to first buy a
ticket at the metro station and then take Line 2. The good thing
about this option is that metro travelling in Shanghai is
pretty easy for foreigners as all stations are signed out in
letters.
Overall the journey time of this option is around 2h. So
unless you really want to sample the feeling of travelling for
7 minutes at 415 km/h, we recommend Option 1 by bus.
\end{itemize}
\subsection*{From Hong Qiao Train Station to Nanjing Nan via
High-Speed Train}
The airport bus will stop directly in front of the southern
part of the Hong Qiao train station. As background, train
stations above the village level in China are organised more
like an airport, than the more sleepy train station you might be
familiar with. Therefore you first have to go through a
security gate where luggage is checked and you padded by a
security guard. The security guard might be of either sex and
this is seen as normal by Chinese. The entire check is done
orderly, but appears to be only a token check and so
fortunately is very speedy.
Next you need to buy a train ticket. There are ticket
counters, see left below, signed out in the main hall.
\begin{center}
\includegraphics[scale=0.8]{travel_guide/image038.jpg}
\includegraphics[scale=0.8]{travel_guide/image040.jpg}
\end{center}
\noindent You have to queue on the longer queue and buy a
ticket for Nanjing Nan (Nan stands for South station). You
will need to show your passport in order to buy a ticket. The
ticket will cost around 135 RMB and looks like this:
\begin{center}
\includegraphics[scale=0.3]{travel_guide/ticket.jpg}
\end{center}
\noindent The G-Number (G42 above) stands for the train
number, which identifies the train also on the large displays
at the hall. Below is the date and departure time, 2015-08-12
and departure time 10:28. To the right is the coach number
(14) and seat number (09C). Just below is the sign that the
ticket above is for second class (-\ -). For the short
duration of the trip there is no real need to buy a ticket for
first class. On the top right-hand corner is the platform
signed out (10A).
Next you have to wait for your train on the main concourse of
the station. On the main display, the platform of your train
will be displayed 30 minutes before departure in case it is
not on the ticket. Assuming you have some time, rest for a
moment and take in the atmosphere of a typical Chinese train
station\ldots Once you know the platform, go to the gate. Be
careful, the gates are nestled between the shops and might be
easily overlooked. For each platform there are two gates
labelled `A' and `B', respectively. `A' stands for the front
of the train and `B' for the rear -- you know which one to go
from the coach number on your ticket. When the gates are
opened for train you need to show again your passport
verifying that it is you who is travelling on the ticket. The
journey to Nanjing Nan takes around 1h.
\subsection*{Nanjing Nan Railway Station to the Hanyuan Hotel}
Like in the section for travelling from Nanjing Lukou Airport
there are three option you can take. The only difference is
that the train station has a different taxi stand, which is
signed out at the station. At the taxi stand you need to take
a yellow taxi that goes to ``Nanjing Downtown''.

\chapter{Conference Programme}
\section{Schedule of the Excursion}
On Wednesday afternoon there will be the traditional ITP
excursion, this time to a Chinese garden in Yangzhou and the
Slender West Lake. You might like to not a few points:
\begin{itemize}
\item The conference session will end at 11:30, and you
should finish lunch no later than 12:20 in order to get
to the hotel lobby.
\item Boarding the shuttle bus is at 12:30 sharp!
\item The first leg of the bus journey takes roughly 40 minutes
to Ge Yuan Garden (meaning Bamboo Garden). This is a
small garden in traditional Chinese style. We will be there
for approximately 1h.
\item After Ge Yuan, we are going to board the shuttle bus again
for Slender West Lake. We are going to enter the Slender West
Lake area from its North Gate. The walking tour at Slender
West Lake will be lead by two guides speaking English.
\item After the walk, we will board boats which will bring
us to the South Gate of the lake.
\item The banquet restaurant (named Lion
Pavilion) is located on the campus
of Yangzhou University. It will take us 5 minute walk
from the South Gate to get there.
\item We expect that the shuttle bus brings us back starting
around 21:30 and we should be back in the hotel by 23:00.
