I think this trip is do-able, but would appreciate feedback in case I've overlooked anything. I will use TWOV for this trip.
Day 2 - Visit Cangyan Shan and stone village, take the train to Beijing. Stay overnight in Beijing.
Day 3 - Fly out of Beijing to Canada.
Question - Does anyone know what I should look for in Tianjin airport to get TWOV? I haven't been able to find much info on where to go when I land.
