The origin of "2 15" is the supervision telephone number 22 1 1504 of Thailand-China Quality Protection Association. In 2005, Thailand's mainstream reception agencies for China tourists set up the "Thailand-China Quality Protection Association", with the presidents of Thailand-China and Thailand-Taiwan Tourism Associations as the heads of the quality protection associations respectively, and China sent a resident in Thailand to supervise the telephone calls, so it was called the 2 15 quality group at that time. If the complaint phone number is not indicated in the guest's itinerary, it is a fake 2 15 quality group. Many people don't know the origin of 2 15, so it is a misunderstanding to say that they are also 2 15 quality tourists.
"2 15 quality tour series" has formed its unique definition today. The core definition of 2 15 is the concept of "double indemnity, no head fee, five boats". The concepts of "two" and "one" are unchanged in different lines, and the concept of "five" will be interpreted differently. For example, the "five" in "Extraordinary Thailand" is: the five-star island "Moonlight Island"; Five boats "Bana Dolphin European Carnival, Oriental Princess Night Tour in Siam Bay, Gui Jiang Raft Rafting House Night Tour, Crocodile Lake Adventure Boat Race, Zhaopiye Chao Phraya River Night Tour". The "five" in Mambapu's product Peach Blossom Island are: Peach Blossom Island, a five-star island; Five boats "European Carnival, Crocodile Lake Boat, Showa Cliff, Peach Blossom Island Cutthroat Island Boating, Pan-Asian Bay Long Tail Boat".
