In 1935, Portugal introduced a standardized model for the coats of arms of its colonies, each featuring a vertically divided shield. On the left side, a white field bore five small blue shields with five white dots each, symbolizing the "Cinco Quinas" and representing Portugal. The right side was customized for each colony: for Macao, it showed a golden dragon above green and white waves, reflecting Chinese cultural elements and the city’s maritime character. The entire shield was set on a golden armillary sphere — a traditional symbol of Portugal's Age of Exploration — and topped with a golden mural crown adorned with armillary spheres and crosses of Christ, emphasizing the colony’s overseas status and historical significance as a bridge between East and West.

The coat of arms of Portugal is commonly known as the Cinco Quinas (Five Quinas) or simply the Quinas, referring to the five escutcheons in the shape of a cross, each containing five bezants on the Portuguese shield. In the late 14th century, the number of bezants was standardized to five, with later interpretations symbolizing the five wounds of Jesus Christ. The shield is supported by seven golden castles, representing the Moorish fortresses captured during the Reconquista. Behind the shield is an armillary sphere, a navigational instrument that signifies Portugal's prominence during the Age of Discovery.
