Depending on how much time you’ll have there, after you do the usual tourist things in Beijing try to spend some time away from the big east coast cities and tourism. I really liked Chengdu in Sichuan. Mostly Chinese tourists and few Westerners. It’s always good to know at least a little bit of the language as well. 12 months ago
Your question allows many answers, not necessarily 'where should I go'. So after my 3 visits, all in all close to 5 months in China, I will only will answer as to general advise.
1. You cannot prepare enough. I've got a paper, where all my hotel addresses are on it in English AND Chinese, and how to get there. English is mostly useless if you need to ask to go anywhere.
2. It is worthwhile to learn a tiny bit of Mandarin and some basic characters such as numbers (and the handsigns they use for it), east/west/south/north etc. Use a good translator app to communicate, otherwise.
3. Come prepared for the big firewall, with a working VPN (there are numerous ones, but best pay for one). I also have back ups, in case it lets you down. E.g. other than my google account, I also install outlook (no VPN needed), Bing as search engine, and maps other than Google maps (although they are the very best, but often have let me down in China).
4. I now pre-order my Sim card with Unicom, and it awaits me in my first hotel. That means, I have immediately access to maps etc, and don't loose a day to find a shop that will sell it to me, install it etc, which was difficult even in Shanghai. All hotels/hostels have WiFi, and 2 Gigs should be enough for about 1 month, if you are careful. I only ever buy data.
5. It is useful to install WeChat, again, no VPN needed, and replaces phone calls if you have to communicate with Chinese people. They all have it. My partner back in NZ also installed it, and it was the easiest way to keep in touch with him.
6. Forget about credit cards, except if you stay in top hotels. For us, ATM withdrawals (they are everywhere, but not always working) are quite expensive, and I very much enjoyed my last holidays when I brought cash with me and didn't have to worry finding the next working ATM. I carry it on my body around my waist, invisibly, always, but that is not everyone's preference.
7. Book hotels in advance (C-trip, Agoda, Booking.com). Remember, some trains also need booking in advance. Bus Terminals are often hidden behind huge buildings. 12 months ago
To expand on the excellent answer above (having returned from China 2 days ago...)
-The firewall means you will have spotty access to email at best, and likely NO access to facebook or google (to include Google maps). A VPN can get you around this. Without it, be sure to let folks know you'll be "off the grid."
-Credit cards--as above...you'll need cash at all but the fanciest locations. Be prepared. My ATM card worked well at the Bank of China ATM's, but failed at 2 others. Fees from my bank were a $4.78 international transaction fee and an ATM fee of $1.00 per withdrawal, so not low, but not outrageous.
-Most toilets outside of your hotel and the airport won't have toilet paper, soap, or paper towels. You'll throw all toilet paper into a wastebasket near the toilet. Additionally most are "squatty potties" as my 3 year old calls them. Carry toilet paper and wet wipes.
-Unlike Japan and many other countries most Chinese don't seem to speak English. Either plan for a guide or ensure you have locations written down clearly in Chinese for the taxi drivers.
-We wish we had allotted more time in Shanghai. We only gave ourselves one day there and easily could've enjoyed another 1-2 days, particularly with the European feel in the "Concession areas" and fabulous food we found.
-Be aware that a visa can be painful to obtain and check fees ahead of time (they were pricier than we anticipated for our family of four!) 12 months ago
Yes, China is good place for travelling. The Great Wall which is known by people all the world is located in China. Beijing, Hong Kong, Chengdu and Nanjing are the famous historical attractions in China. There are so many travel companies are available in Market. I have gone only Beijing. When I had gone to Beijing I travelled by the help a tour guide namely (Beijingtransfertours(dot)com). The Forbidden City, the Summer Palace are Great wall are top tourist places in Beijing. 12 months ago
