Hi, i'm leavin to tianjin in mid march....i'm thinkin if it is wise to take a train or cab to beijing since there are 6 of us here???....is mid march considered winter or spring???....and the most important thing is will there be any communication problem in tianjin and beijing..since none of my family member know chineese and we hope people in tianjin and beijing can communicate in english (at least for our basic needs)...tqvm in advance
