Kuxun, which became famous due to the "train ticket search" at the beginning of 2006, announced yesterday that the company would transform into a travel search engine integrating five major search businesses including train tickets, air tickets, hotels, holidays and scenic spots, and put into operation a new domain name "Kuxun.cn", recommending all kinds of preferential tourism information on the home page. The real estate and employment search engine businesses would take a back seat.
