The FuJian region is as yet a relatively unexplored as can be see on this website, they do not record any Hotels in Wu Yi Shan on their website (though there are some very good 4* Hotels), so you can be sure that you will be exploring an un-tramelled region of China. As the site states:
“Fujian is blessed with a rich history, famous historical sites and beautiful natural landscapes. These make Fujian a unique tourist attraction. Howeve, it is not yet a much worn traveler's path”
