Dear Jim
I am glad that you will come to Beijing this winter break. Beijing is cold in winter. The temperature is around twenty degrees below zero, so prepare some warm clothes. There are three ways to come Beijing from Wuhan--car, train and airplane. Needless to say, car is the slowest, but it is the cheapest. The train is faster than the car, but the airplane is the faster. The airplane costs a lot more than car or train. I suggest you to take train because it's not very slow and the price is acceptable.
