Providing much-needed relief from the smog and dust that plagues many Chinese cites, Hainan's lasting clear days make it one of the hottest domestic tourism destinations in the winter.

Statistics from the Hainan Tourism Commission showed that the province welcomed more than 1.9 million tourists during the Spring Festival holiday from Feb 9 to 15, an annual growth of nearly 41 percent.

The commission predicts that over the course of this year, Hainan will receive 36.52 million visitors, an annual increase of 10 percent.
