215 years ago today, September 16, 1810 (August 18, 1810, the lunar calendar), Mexico's Independence Day. On September 16, 1810, Hidalgo (1753-1811), leader of the Mexican independence movement, sounded the church bell and summoned nearby farmers and urban poor. Hidalgo, who was nearly 60 years old, stepped onto the podium and solemnly declared: "For us, whether kings or taxes, they no longer exist. These hateful taxes, a symbol of cruelty and slavery, have oppressed us for three centuries." Then he asked loudly,"Do you want to be free?" Three hundred years ago, the hateful Spaniards seized the land of our ancestors. Are you willing to take it back?" The crowd shouted in unison: "Long live independence!" "Hang colonial bandits!" This is the famous "Dolores Call" in Mexican history, which kicked off the Mexican War of Independence. Later, during the War of Independence, Hidalgo was betrayed by traitors and captured, and died heroically on July 30, 1811. Later, in order to commemorate Hidalgo, the Mexican people designated September 16, the day when the "Dolores Call" was issued, as Mexico's Independence Day. Mexico is located in the northwest of Latin America. It is an ancient civilization. It used to be the hometown of the Indians. In 1521, it became a colony of Spain, and a large number of European talents came here. Among the country's current population, Indo-European mestizo accounts for 91.7%, and Indians account for 7.8%. Legend has it that long ago, Indians living in northern Mexico went to the south to find a new homeland under God's instructions. God told them that there was a place where an eagle was standing on a cactus, with a snake in its claws. The place was very rich. Under the leadership of their leader Tenochi, a hummingbird guided them. After many hardships, they finally saw the scene God had said on an island in Lake Tescoco. They lived and worked hard to create a city called Tenochtitlan, which is today's Mexico City. This ancient legend embodies the Mexican people's beautiful desire to pursue happiness. Therefore, on today's Mexican flag, there is a pattern like this: an eagle standing on a cactus, holding a snake in its mouth and grasping the snake's body with one claw. It comes from this ancient legend.
