471 years ago today, on January 25, 1554 (December 22, 1553 in the lunar calendar), the city of Sao Paulo, Brazil was established. Sao Paolo is the largest city and largest industrial center in South America, the capital of Sao Paulo State, and one of the four largest cities in the world. It is located on a plateau with an altitude of more than 800 meters on the edge of the large cliff of the Mare Mountains in the southeast of the border. It is 63 kilometers away from the outer port in the southeast. The Urban area covers an area of 1624 square kilometers. Greater Sao Paulo, including suburbs, reaches more than 2300 square kilometers. The population of Greater Sao Paulo exceeds 13 million. Sao Paulo was originally an Indian village. On January 25, 1554, Portugal colonists came here and found that its geographical location was ideal. They built a town on a large scale. Because this day happened to be the day when the Catholic Church commemorated Saint Paul, they named the town Sao Paulo. In 1711, the city of Sao Paulo was established. In 1822, Brazil declared its independence here. By 1880, Sao Paulo was still only a town with an area of 2 square kilometers and a population of 40,000. However, by the end of the 19th century, due to large-scale coffee planting in nearby areas and the influx of foreign immigrants, the town began to develop rapidly. By 1940, the city's population has exceeded 1.3 million. According to relevant reports, Sao Paulo is the fastest growing city in the world.
