Children salute the national flag at the flag-raising ceremony at the start of the new term on Beigang Island, South China's Hainan province, Sept 1, 2014. The islet, about 400 hectares, once lost contact with the outside world when Typhoon Rammasun, one of the strongest typhoons, battered Hainan in July. There is only one school on this island, with four teachers, 19 students and a security guard. [Photo/CFP]
