Customers select watches at Haitang Bay duty-free shopping center in Sanya, south China's Hainan Province, Jan. 31, 2016. The popular holiday island of Hainan will relax limits on offshore duty-free shopping from Feb. 1, allowing non-locals to buy duty-free products worth up to 16,000 yuan (2,442 U.S. dollars) before they take flights to leave the island, without any restriction on the number of purchases. The island's two duty-free shops will also launch online services that will enable travelers to order on the Internet and pick the products at the airport. [Photo: Xinhua/Guo Cheng]
