Ten travel sites in Hainan province have formally entered into an alliance to set up a league to develop Hainan's tourism network marketing services.

The league's slogan is "make the partners stronger". The first ten websites are: haihainan.com, hiholiday.com, 100t.com, ziyouren.com, hntour.com, hnsss.com, 527ziyou.com, hainan.cc, nanshan.com, and tohainan.net. All of these are reported to be among the most influential tourism consulting sites with the most traffic. The league will bring together the technology strengths of its members to develop a public reservation system that can be shared by all its members.

There are six sections on the league's website, covering domestic travel information, tourism products recommendation, introduction to the league's members, the booking and service platform, training and further education. Travel sites in Hainan that wish to strengthen their position can apply online to be part of the league.
