What is the name of the estuary surrounded by the delta containing Changzhou Island?
Pearl River Delta The Pearl River Delta Metropolitan Region (PRD), also known as Zhujiang Delta or Zhusanjiao, is the low-lying area surrounding the Pearl River estuary, where the Pearl River flows into the South China Sea. It is one of the most densely urbanized regions in the world and is an economic hub of China. This region was also the source of much Chinese emigration from the 19th to the mid 20th centuries, including to the Western world, such as the US, Canada, Australia, Latin America, and much of Southeast Asia, where they formed many Chinatowns. Today, much of the Chinese diaspora traces their ancestry to this region.
Port of Xiamen The Port of Xiamen is an important deep water port located on Xiamen Island, the adjacent mainland coast, and along the estuary of the Jiulongjiang River in southern Fujian, China. It is one of the trunk line ports in the Asia-Pacific region. It is ranked the 8th-largest container port in China and ranks 17th in the world. It is the 4th port in China with the capacity to handle 6th-generation large container vessels. In 2013, Xiamen handled 191 million tons of cargo, including 8.08 million TEUs of containers. On 31 August 2010, Xiamen Port incorporated the neighboring port of Zhangzhou to form the largest port of China's Southeast. This was a relatively uncommon case of ports merging across jurisdictions.
