中国入境全流程：签证、交通与必备App | Entering China: Visa, Transport & Must-Have Apps

签证与入境 / Visa & Entry

2024年起，中国对多国实施144小时过境免签和15天免签政策。持普通护照的游客可在北京、上海、广州、成都等城市免签入境。需准备：有效护照（6个月以上有效期）、返程机票、酒店预订确认。入境时填写健康申报（可通过"海关旅客指尖服务"小程序提前填写）。

Since 2024, China offers 144-hour transit visa-free and 15-day visa-free entry for many nationalities. Travelers can enter visa-free through Beijing, Shanghai, Guangzhou, Chengdu and other cities. Prepare: valid passport (6+ months validity), return ticket, hotel booking confirmation. Fill in the health declaration upon entry (or use the "China Customs" mini-program in advance).

机场到市区交通 / Airport to City Transport

北京大兴机场：地铁大兴机场线到草桥站（35元，19分钟），转地铁到市区。出租车到市中心约150-200元。上海浦东机场：磁悬浮到龙阳路（50元，8分钟，时速430km/h值得体验），转地铁。地铁2号线直达市区但耗时长（约1.5小时）。广州白云机场：地铁3号线直达市区（7元，约50分钟）。成都天府机场：地铁18号线到市区（约10元，50分钟）。
