Caoqiao, China

This subway hub has a population of 65,243 people, but don't let that fool you - the bureaucracy and logistics can be a persistent headache. The station provides access to multiple subway lines, including the Daxing Airport Express, but the layout is a maze of underground platforms and exits. While the airport check-in service is a convenient perk, the overall experience is more frustrating than functional. Unless you're a seasoned urban commuter, Caoqiao is probably not the expat oasis you're envisioning.
