what month is the best time to visit xiamen as tourist ? could you give as hotels near the city ?

It is mild and pleasant most of the year because the city has a subtropical monsoon climate. In this case, the whole year round is good time to visit Xiamen except that typhoons influence the weather four to five times during the months from July to September.
Travelling to this city, you should not miss Gulangyu Island, South Putuo Temple, and Jimei.
