This combination photo taken on Dec. 30, 2015 shows the scenery seen from the first high-speed train circling the Hainan island from Haikou to Sanya, south China's Hainan Province. The 345-km Western Ring Railway in Hainan was put into operation on Wednesday, completing the world's first high-speed train line circling an island. The western stretch, with a designed speed of 200 km per hour, has 16 stops in six cities and counties, linking provincial capital Haikou with Sanya, a tropical tourist spot.
