The trip to the northwest, from Hohhot to Yinchuan, from Yinchuan to Lanzhou, in Yinchuan Airport, I was most impressed by the airport VIP hall that was much better than I thought. I thought that the city was not big, the VIP hall was estimated to be not big, I didn't expect the space to be large, and there were many functional areas, especially the chairs that could be almost flat, so it would not feel cramped and noisy. Meals will also be available. Overall great
