How it is used
- Means 'along the way / en route' - 沿途风景很美 (yántú fēngjǐng hěn měi) the scenery along the way is beautiful.
- It describes things encountered during a journey, so it pairs with sights, stops, and events on a trip.
- Contrast 沿线 (yánxiàn), which is tied to a fixed line/route; 沿途 is about the experience of traveling through.
