Upon early-morning arrival, you can take night buses (operating after 23:15, covering areas like Guomao and Beijing Railway Station) or choose taxis/ride-hailing services (24/7, 20% night surcharge from 23:00–05:00, fare 150–200 RMB, 40-minute drive). If arriving very late, stay at nearby airport hotels (e.g., Yaduo S, Mingzhu, with free shuttle services) and enter downtown the next day.
