Macao The Macao Special Administrative Region of the People's Republic of China, referred to as Macao, is one of the two special administrative regions of the People's Republic of China.

It consists of four parts: the Macau Peninsula connected to mainland China, and Taipa, Coloane and Cotai on the South China Sea at the mouth of the Pearl River.

It is connected to Gongbei of Zhuhai City in Guangdong Province to the north and faces Wanchai and Hengqin, both of which belong to Zhuhai City, to the west.

The Macau Peninsula and Taipa are connected by three bridges, namely the Governor's Bridge of Gallepi, which was opened in October 1974 (named after the name of the then Governor Gallepp, commonly known as the Macau-Taipa Bridge or the Old Bridge, from April 8, 2005

Temporarily closed for half a year for renovation works, only public transportation has been restored to use), the Friendship Bridge opened in March 1994, and the Sai Van Bridge opened on January 9, 2005 (it is also the only double-decker bridge in Macau)

all-weather bridge).

In addition, there is the Lotus Bridge, which connects Cotai City with Coloane and Taipa and Hengqin Island in Zhuhai City. It is the second port connecting to mainland China. There is also an undersea tunnel from Macau to Taipa that is expected to be completed in the second half of 2009.

To the east, it is 60 kilometers away from another special administrative region, Hong Kong (when the weather is good, you can overlook Lantau Island in Hong Kong), separated by the Pearl River Estuary in the middle; and one end of the planned Hong Kong-Zhuhai-Macao Bridge will be connected to the Oriental Pearl Tower in the northeast corner of Macau

.

The Macao Special Administrative Region is located on the southeastern coast of China, on the west bank of the Pearl River Estuary and south of the Tropic of Cancer.

To the north is the Macau Peninsula connected to mainland China, while to the south is the large island composed of Taipa, Coloane and Cotai. It is an island city and has no official name yet.

The island was originally Taipa Island and Coloane Island. However, after the Cotai-Taipa road project was launched, due to reclamation and the large amount of sediment brought by the water flow of the Xijiang River, the seabed between the two islands became shallower and shallower.

There are also more and more lands.

Seeing this, the authorities carried out reclamation projects in a planned manner, and the resulting land became Cotai City.

According to the measurement of the Cartography and Cadastral Bureau, the reference geographical coordinates of the stone pillar next to the telescope of Guiyang Mountain Observatory are: 22°11'47" north latitude, 113°32'58" east longitude, and an elevation of 91.2 meters.

The highest point in Macau is the top of Shek Tong Hill in Coloane, where the Mazu Statue is now located (elevation 172.4 meters).
