You can take a shuttle bus to the train station and take a high-speed train to Shijiazhuang Railway Station (16.5) at 20:41 at the latest. You can also take a bus. I haven’t done it yet. I don’t know how long it takes. There is a service phone number in the photo for consultation.
Go fast. Take the high speed and go through Zhengding all the way to the city. It only takes more than ten minutes to drive from the airport to Zhengding!
