The island is situated on an important navigation route that connects China, Japan, Thailand and Philippines to Vietnam. Along two sides of the island are tens kilometres of sand beaches. This is the endless resource for glass making which the sea gives to man and it is also the extremely interesting tourism.
Since the 11th century, Quan Lan had been one of the centres of the ancient commercial port of VA?n Don, which was animated and prosperous at the time. Today, there are still many vestiges linked to the ancient commercial port. This also explains why the island, lying deep in the sea, has the large pagodas and archaeological sites seen today. On the island there is the Quan Lan Communal House built in the 18th century; exceedingly beautiful and almost entirely preserved. Next to it is Quan Lan Pagoda (Linh Quang Tu), which is dedicated to Buddha and God LiA?u Hanh. The pagoda also worships the statue of old Hau, a local person who made lots of contributions to the construction of the pagoda. The statue features a gentle and cheerful old woman, which adds an original character to the pagoda. Beside Quan Lan Pagoda lies NghA? Quan Lan (Duc Ai??ng) Shrine, which is dedicated to Pham CA?ng ChAi??nh, a local people who participated in the historical VA?n Don battle against the Yuan invaders. He was later honored as a god. Quan Lan has many valuable sea products such as octopuses, butterfish, mackerel, holothurian, shrimp, and sA?i sA?ng.
