Tourists stand on a deck in the tourist resort island of Wuzhizhu, about 50 kilometers from Sanya, in South China’s Hainan Province on Tuesday. China’s domestic tourism is booming as evidenced by an estimated 150 million people who took to the road, rail and air during this year’s “golden week” Labor Day holiday in May. The government is considering changing the country’s three holiday weeks and introduce long weekends to cope with traveler congestion. SD-Agencies
