Brazil's national flag can be said to be very complicated. The length-height ratio of Brazil's national flag is 10:7, the background color is green, and there is a yellow diamond on it. There is a blue circle in the diamond, and there is a white ribbon in the circle with "order and progress" written in Portuguese. There are also 27 stars of different sizes in the prototype.

Brazil's national flag evolved from the flag of the Brazilian Empire, and the green background and yellow diamond in it were inherited from the flag of the Brazilian Empire. Green represents the forest, and yellow represents the minerals. However, another way of saying this is the colors of the flags of the two families of Emperor Pedro I and Empress of Brazil, which is regarded as the union of the two families.

Now look at the circle inside, the stars inside and the white ribbon. The circle represents the earth and the white belt represents the equator. The stars of different sizes above represent the number of first-level administrative regions in Brazil.

Brazil has 27 first-class administrative regions, so there are 27 stars. The location of the stars is based on the location of these administrative regions in Brazil. The size of the stars represents the area of the administrative regions. The bigger the area, the bigger the stars. Also, these 27 stars belong to the Southern Constellation, representing nine constellations: Nanhe III, Canis Canis, Canopus, Hornet I, Ophiuchus, Southern Cross, invivo, Southern Triangle and Scorpio. The number of stars in this area will change with the number of first-level administrative regions in Brazil. At first, it was 2 1 star, and then it increased continuously to 27 stars.

Some people will say that the stars are constantly moving and the constellations are constantly moving. Why is the constellation above Brazil unchanged? This is because this constellation adopts the arrangement order of the stars on 1 1 month 15. 1 1 month 15 in 889, Brazil * * * was formally established, so everyone decided to use this day's constellation arrangement.

In fact, the meaning of the Brazilian flag includes other meaning in addition to the above. For example, the yellow diamond, and some say that it does not represent mineral resources, but represents gold. In any case, it is no exaggeration to say that the Brazilian flag is the most complicated flag.
