Came back from China a week ago, visiting family, and between Beijing Capital airport and our final destination we didn’t have to step outside (into the heat) once. The Capital Express train is brilliant. Quick change on the subway and then a few stops to Qianhe Station, then on to the high speed rail network for an hour to our destination. Exactly the same on the way back, got us to the front of the Hainan Airlines check in queue 20 mins before check in opened. Brill! Travel Threads
