How to find the most affordable tourist routes?

Find a few more apps to compare, Honeycomb Free Travel+Baidu Travel: very detailed travel guides, precautions, modes of transportation, etc. And I will recommend you the corresponding places according to the season/the scenery I want to see (island/country/shopping/skiing), which is also the most used app for my itinerary planning. Duoqu+Tuniu: I usually use this reference route to provide a large number of tourist route products. If my friend wants to join a group, this is not bad either.
