There are no rivers in Macao, but why do you use Haojiang to refer to Macao?

Macao used to be a small fishing village. Its real name is Haojing or Haojing 'ao. Macau and its vicinity are rich in oysters, so later generations changed the name to a more elegant "Hao Jing". Haojiang is a river in the South China Sea system. It enters the South China Sea from Guang 'ao Bay (Qiwang Bay) and is closely related to Macao, so it is also called "Haojiang".

At that time, because the berth could be called "Macao" and there were cross gates outside Australia, it was collectively called Macao. Foreigners call Macao because it originated from Marco, which means Mazu Tempel among the population of Macao at that time. The Portuguese who arrived at that time later learned the word Macao and became the official foreign language name of Macao.

Macao is located on the north shore of the South China Sea, on the west side of the Pearl River Estuary, bordering Zhuhai City, Guangdong Province in the north, 63 kilometers from the adjacent Hong Kong Special Administrative Region in the east, and the rest are adjacent to the South China Sea.

Extended data

Macao used to be an island at the southern tip of Zhongshan City (formerly known as Xiangshan County) in Guangdong Province, standing in the sea, no different from the contemporary offshore islands. Later, due to the sediment alluvial of the Xijiang River, a sandbar (Liangan, now Guanzha Road) was alluvial between Macao and the mainland, which was connected with the mainland and became a peninsula.

The reclamation project started at 1863, which is the main source of flat land for Macao. The reclamation project has greatly changed the outline of Macao today hundreds of years ago, and also made the coastline tend to be straight and tidy.

Macao is located at the junction of salt and fresh water on the west bank of the Pearl River Estuary, and there are a lot of sediment deposits from Xijiang River in the surrounding waters, which makes the shallows around Macao widely distributed and shallow in water depth.

On the whole, if the eastern end of Macao Peninsula, Macao Peninsula and Macao Ring Road are taken as the boundary, the waters in the eastern part of Macao are deep, and the other waterways in the western part are shallow except the inner harbor waterway and Jiamakou waterway, so the main modern passenger and cargo terminals in Macao are located in the east.
