Ha Long, one of the World Heritages, comprises thousands of big and small islands. Each one has its own characteristic with various caves: Sung Sot Cave,Thien Cung Cave, Trinh Nu Cave. Tuan Chau Island is the only soil island of all. It is not only a place having beautiful natural surroundings: pine trees, lakes, beautiful beach…but also where President Ho Chi Minh chose to be the relax place of other State officials' and his when they came here in 1959.

On the total area of 400 ha, Tuan Chau has the population of 1500. As planned, the total area of Tuan Chau will be widen to 675 ha. It enjoys the advantage of having both road and river transportations. It is about 18 km away from National Highway No.1. This route is an important blood vessel of the robust Hanoi – Hai Phong – Quang Ninh economic triangle. It takes about 3 hours from Mong Cai ( 2 hours by boat) and 1 hour from Hai Phong.

Tuan Chau island’s name is the combination between ‘linh tuan’ (the patrolman) and ‘tri chau’ (district chief) because in the feudal time, the royal army set up a guard station here to patrol and defend the borderland. Prior to 1999, the island's residents suffered from a very modest living standard.There was no power network and no clean water. Roads were only trails and there was no mechanical means of transportation. Tuan Chau was a very poor town where fishing with very rudimentary tools is the only means of living.

The emergence of the Au Lac company has completely changed the scenery of Tuan Chau. Living conditions have also improved since then.
