Macao was called "Haojing 'ao" in ancient times. Over the centuries, many place names have been formed, mainly including Macao, Xiangshan 'ao, Haojiang, Haojiang, Jinghai, Majiao and Macau Street. Hao Jing, originally an oyster mirror, is the real name of Macau; It is named after the circular bays on the east and west sides of the Macao Peninsula (after many times of reclamation, the coastline gradually becomes flat). Whenever there is a calm moonlit night, the sea water is silver and smooth as a mirror, just like the inner wall of an oyster shell. Macao and its vicinity are rich in oysters, which are called oysters in Cantonese, and the inner wall of their shells is smooth and bright as a mirror, so they are called oyster mirrors. Macao got its name from this. Qu Dajun, one of the three outstanding figures in Lingnan in the late Ming and early Qing Dynasties, wrote in his Cantonese New Talk: "The oyster mirror ... goes to the southeast of Xiangshan 120, and the south and north bays are surrounded by seawater." Later, because of the vulgar word "oyster", the oyster mirror was changed to Hao mirror. The book "A Brief Introduction to Macao" published during the reign of Qing Qianlong said: "There are two bays in the north and south, five or six miles in the east and west, or the South Ring Road. The second bay gauge is as round as a mirror, so it is a mirror. "

In addition, because the Beibu Gulf in Macau is only a section of river, the nickname of Haojiang comes from Haojiang. There are also aliases such as Haijing, Jinghai and Jinghu, which are also evolved from Haojing. Macao got its name because Hao's mirror became "Macao" and looked like a "door", so it was collectively called "Macao". Macau has always been the territory of China, which was originally under the jurisdiction of Xiangshan County (now Zhongshan City, Zhuhai City). 1535 (14th year of Ming Jiajing), the Portuguese bribed local officials in Guangdong and obtained the right to dock ships and conduct transactions in Macao. 1553 (thirty-two years of Jiajing), he went ashore to live on the grounds of sun flooding. After the First Opium War, the Portuguese took the opportunity to expand the territory occupied in Macao. 185 1 and 1864, taipa island and coloane island were successively occupied. From 65438 to 0887, Portugal coerced the Qing government into signing the Draft Convention of the Sino-Portuguese Conference and the Sino-Portuguese Beijing Treaty, stipulating that "Portugal's permanent existence in Macao and the place where Macao belongs are no different from Portugal." Since then, Portugal has occupied Macao and included it in the Portuguese territory.

After the establishment of People's Republic of China (PRC), according to the joint statement of the Chinese and Portuguese governments on the question of Macao, the China government will resume the exercise of sovereignty over Macao on February 20, 1999. 1993 On March 3/kloc-0, the China government promulgated the Basic Law of the Macao Special Administrative Region of the People's Republic of China, stipulating that the Macao Special Administrative Region is directly under the Central People's Government and enjoys a high degree of autonomy, including administrative power, legislative power, independent judicial power and final adjudication power. The Macao Special Administrative Region will not implement the socialist system and policies, but will maintain its original capitalist system and way of life for 50 years.
