TripAdvisor

TripAdvisor is the world's largest user-review platform for travel, with Viator as its dedicated tours-and-activities booking arm. For China travel, it's most useful as a research tool paired with activity booking.

What they offer for China travel:

• Reviews & ratings: Massive archive of user reviews for China attractions, hotels, restaurants, and tour operators — useful for vetting options before booking.

• Forum & Q&A: Active traveler forums where past visitors answer China-specific questions (visas, train travel, specific cities).

• Tour booking (Viator): Bookable day tours, multi-day tours, and experiences in major Chinese cities, run by local operators.

• Aggregated listings: Pulls together hotels and attractions with pricing and availability, useful for comparison shopping.

Best for: Travelers who want to research and vet China options via crowdsourced reviews before booking, and who want bookable day tours in major tourist cities — less suited to fully custom or multi-region bespoke itineraries.

Coverage: Strongest reviews in tier-1 tourist cities (Beijing, Shanghai, Xi'an, Chengdu, Guilin, Hong Kong). Thinner reviews and tour inventory in secondary cities and remote regions.
