1.As a foreign traveller , there’s certainly one thing that you need to bring with you while you are travelling through fast train or bullet trian, which is your passport. 2. As you walk out of the airport or train sation, go straight to the taxi  area don’t go with the people that approach you. ( A screen shot with your hotel address indicated is neccessory because the drivers doesn’t understand English) 3. While booking a hotel , try to book in the Centre districts of  the city. Cuz the city are actually very big, most of the facilities and entertainments are in the city centre. 4. For your convinience , if needed is always good to have someone local to guide you. Not only save you a lot of time but also make you day easier and more productive.
