About the Flag
"Macao, also known as Macau, is a Special Administrative Region of China, located in western Pearl River Delta. Therefore, the national flag hoisted in the region is the Five-starred Red Flag of the People's Republic of China. However, Macao has a regional flag, bearing the five stars found on the flag of China.
The regional flag of Macau consists of a green field with a lotus flower between a stylized bridge and water in white (below) and an arc of five gold, five-pointed stars: one large in the center of the arc and two smaller on either side. The lotus is the floral emblem of Macau. The three petals represent the peninsula and two islands that make up Macau. The five stars are those on the flag of China, signifying the region's relationship with China." (source: worldatlas)
