• Pinyin: yī lù shùn fēng
• English Translation: Have a pleasant journey (Smooth sailing)
• Idiom Composition: 「一」（The whole; entire）＋「路」（Road; journey; path）＋「顺」（Following; in the same direction as (referring to the wind)）＋「风」（Wind）
• Meaning: A common parting wish for someone embarking on a journey, expressing the hope that their travel will be safe and without obstacles. Literally, it means 'may the wind be at your back throughout the entire journey.'

2. Detailed Meaning and Nuances

「一路顺风」 contains the following nuances:

• Wishing for Safe Travel: It is used as a formulaic greeting for anyone heading to a distant location or starting a vacation.
• Metaphorical Success: Beyond physical travel, it can imply that a new venture, such as a job transfer or a new challenge, should proceed without hitches.
• Note on Air Travel: In modern usage, some people avoid using this phrase for flights because a 'tailwind' (顺风) is technically unfavorable for takeoff and landing. They may choose 一路平安 (yī lù píng ān) instead, though most people use the terms interchangeably in casual conversation.

4. Cultural Background and Notes

• Originating from the era of sailing ships, the phrase reflects the historical importance of a favorable tailwind for a successful voyage. This maritime imagery has evolved into a general metaphor for any smooth process.
• In modern times, a minor linguistic superstition exists regarding air travel. Since airplanes require headwinds for lift during takeoff, some meticulous speakers avoid saying 'tailwind' (顺风) to travelers and instead use 一路平安 (yī lù píng ān), which focuses on 'peace' and 'safety' regardless of the wind. However, the majority of people simply view it as a warm 'bon voyage' and do not overthink the physics.
