While the government of Shenzhen uses the name widely, the people and government in Hong Kong continue use the local name .

As the bay is largely enclosed by lands, fresh water from the surroundings are injected to the bay, formed by a large sheer with a shallow shore of wetlands. The margin of fresh water and forms a valuable habitat for a wide variety of life.

The bay's northern shore used to be lined with marshes. As Shenzhen began to develop into a major urban centre, the northern shoreline was to provide land for buildings. Some departments had tried to preserve the endangered environment but mistakenly introduced foreign species of mangrove, which threatened their indigenous counterparts.

The marshes remain largely intact along the southern part of the bay, which is under Hong Kong's jurisdiction. Mai Po is an important for in the area. Pools of former fishing farming is another attraction to birds.

Agriculture and fisheries

Illegal immigrants

Before 1949, Chinese people were free to travel between Hong Kong and mainland China. In order to halt large influx of refugees from mainland China, the Hong Kong Government established border control and compulsory registration of Hong Kong residents was carried out.

As a result, it was harder to migrate to Hong Kong than before and thus many crossed the border illegally. Deep Bay became the main access for illegal immigrants because border controls were harder to enforce at sea. It was relatively easy to cross the bay and there were major roads to the urban centres of Hong Kong. The rural town of Lau Fau Shan was the major landing point.
