Are there any good websites or forums about travel?

Travel websites are divided into several levels and categories. One is comprehensive, one is regional, one is professional, and one is information-based. The ones I often know about are: Lotto, TOM. Ctrip Travel Network, Qutu Travel Network, Qianhe Travel Channel. etc. You can view travel information, travel routes, pictures of tourist attractions, travel methods, travel agencies, hotels, guesthouses and other information above.
