裝一個能用的地圖 Install a map that actually works
這是所有出行的地基。沒有可用的地圖，打車、問路、找店都無從談起。 Everything else depends on this. Without a working map, ride-hailing, asking directions and finding shops all fall apart.
高德地圖 Amap 首選 · 數據最準 Amap 高德地圖 · first choice
國內導航的事實標準。除了駕車/步行/公交路線，它還能直接叫車（聚合了多家網約車）、查實時公交、看擁堵路況、搜附近的廁所與充電寶。Apple 地圖在中國的數據也來自高德。
The de facto standard for navigation in China. Beyond driving, walking and transit routes it can hail rides across multiple operators, show live bus arrivals, traffic conditions, and find nearby toilets and power-bank rentals. Apple Maps data in China also comes from Amap.
百度地圖 Baidu Maps 備選 Baidu Maps backup
與高德功能相當，街景與室內地圖覆蓋不錯。兩個裝一個就夠，建議以高德爲主，百度作爲交叉驗證（比如某條路高德沒收錄，百度可能搜得到）。
Roughly equivalent, with decent street view and indoor maps. One is enough — use Amap as your main and Baidu to cross-check when a place doesn't show up.
Apple 地圖 / 系統地圖 能用，但功能弱 Apple Maps works, but limited
在中國境內可以正常定位與導航（數據來自高德），適合臨時救急。缺點是公交換乘信息不如本地 App 細緻，也無法叫車。
Positioning and navigation work fine in China (powered by Amap data), so it's a decent emergency option. But transit detail is thinner than local apps and you can't hail rides from it.
Google 地圖 在中國不可直接使用 Google Maps not usable on a domestic connection
在未接入國際網絡的普通網絡環境下無法使用，且 POI 數據與國內實際情況存在偏差，導航結果不可靠。請改用高德或百度，並通過合規的漫遊 / eSIM 渠道解決其他聯網需求。
It isn't reachable on a standard domestic connection, and its POI data diverges from reality on the ground, so its routing can't be trusted. Use Amap or Baidu instead, and handle other connectivity through your carrier's roaming or a travel eSIM.
收藏夾當行程表Use favourites as your itinerary
把酒店、景點、餐廳全部「收藏」到高德里，命名成 Day1 / Day2。打車時直接點收藏夾選目的地，不用手打地址。
Star your hotel, sights and restaurants in Amap and name them Day1, Day2. When hailing a ride, pick the destination straight from your favourites — no typing.
截圖中文地址Screenshot the Chinese address
在高德里搜索目的地，截圖保存中文名 + 地址。問路、給司機看、給酒店前臺看，都比說英文有效。
Search your destination in Amap and screenshot the Chinese name and address. Far more effective than English when asking directions or showing it to a driver.
定位漂移要理解Expect GPS drift
高樓密集區 GPS 會偏移幾十米。約車時把上車點選在明顯的地標（地鐵口編號、商場正門），比選「路邊」靠譜。
Among dense towers GPS can drift tens of metres. Set your pickup at an obvious landmark (a numbered metro exit, a mall's main door) rather than "by the road".
