Here's the honest answer from someone who's spent 15 years in the travel industry: don't drink the tap water. Even I don't.\n\nBut it's not a big deal. Every hotel gives you 2 free bottles a day. FamilyMart and 7-Eleven are everywhere — a 1.5L bottle costs about 3 yuan ($0.40). You can also grab them at Trip.com or hotel convenience stores.\n\nWhat I tell my clients: travel with a stainless steel thermos. Most hotels and restaurants have free hot water stations. Great for brewing tea, and it saves you from buying plastic bottles all day. I always fill mine before heading out.\n\nAnd yes, brushing your teeth with tap water is fine. Just don't swallow it. My kids have done this for years without issues.\n\n**Quick tips for first-time visitors:**\n- Buy bottled water in bulk at supermarkets like Carrefour or Walmart for longer stays\n- Use Google Flights or Booking.com to find hotels that offer free water refills\n- For day trips, carry a reusable water bottle and refill at tea houses or convenience stores\n\nBottom line: it's an easy habit to manage. Pack a thermos, grab some bottles, and you'll be set for your whole trip.
