January in Vietnam — events that affect travel
Known cultural, religious, or national events that surge prices, fill hotels, or close businesses during this month. Plan around them, or build your itinerary around the ones you'd like to see.
The largest annual human migration on earth — 300M+ people travel. Mainland China sees mass closures of restaurants, attractions, and shops for ~1 week; transport books out months ahead.
Plan: Travel within mainland China is genuinely hard during this window. Hong Kong/Singapore stay open but very busy. If you can shift dates, do.
