There are many ways to book hotels, trains and flights in China. Most locals will use ctrip or qunar or wechat. The upside of these is usually better service and much better prices.
If you are looking for a simple easy to use method then I suggest Trip.com. This is an English language version of ctrip and yes the prices are higher by around 10-15%, it is all in English, accepts passports, has English customer service and foreign friendly payment methods.
As you can see it is totally in English. You can book train tickets and get the electronic ticket on your phone, book flights in and out of China and book hotels that accept foreign passports.
