Is the Xinjiang International Travel Service buy one get one free reliable?

Reliable. The Xinjiang CITS buy one get one free offer does exist. Tourists should read clearly the terms of the contract and the specific content of the itinerary. Do they need to pay extra for the trip? What are the included items? They should do some research before going. At least they should know the local customs, attractions, temperature, etc. to have a general understanding. If you check the itinerary later, you won’t be deceived. Tour groups are still very formal now.
