Hong Lam village of Xuan Giang commune in Nghi Xuan district, Ha Tinh province is commonly known as the oasis as it is separate from the outside by the Lam River.

Surrounded by the river, the only means of transport to go to the island is simple boats. Currently the village has 200 households, mainly middle-aged and elderly people.

To serve the needs of learning of children in Hong Lam village, Nghi Xuan district authorities built a kindergarten and a primary school on the island.

The branch of Xuan Giang Primary School was built over 10 years ago with eight classrooms. Previously, the school had about 15 students but now there are only nine children attending grade 1, 2 and 4.

The school has four teachers who cross the river to go to school everyday. Sometimes the children are absent from school, or go to the main school on the mainland, so the school has only three students and a teacher.

From Monday to Friday, female teachers have to travel several kilometers, then cross the river to go to the oasis for teaching.

Teachers prepare a pair of rubber boots and a pair of sandals. The rubber boots are used on the boat and the sandals are used in class.
