In 828, two rich Venetian merchants, under the instruction of the Governor at that time, succeeded in stealing the mummy of San Marco from Alexandria Port, hiding him under layers of meat products, transporting him back to Venice, and storing him under the altar of San Marco's Cathedral. From then on, San Marco became the patron saint of Venice. His symbol is a winged lion. From then on, Venice was full of lions. At the entrance of St. Mark's Square, there are two tall columns. On the east column stands a bronze lion, which is the emblem of Venice - the flying lion. The flying lion held a holy book in its left front paw, on which was written a Catholic oracle in Latin: "Mark, my messenger, rest in peace there!" At a glance, Saint Mark and his lion are indispensable to the Governor's Palace.

Venice has been an independent water republic for a long time. Its political power is jointly controlled by the governor and parliament, and it has the characteristics of both autocratic and republican regimes. St. Mark's Cathedral is said to be named after the burial of St. Mark, the disciple of Jesus (the apostle): St. Mark's Square, St. Mark's Cathedral, and the famous St. Mark can be seen everywhere in Venice. Saint Mark, the author of the Gospel of Mark in the New Testament, died in Egypt in 67 BC.

Since ancient times, St. Mark's Square has always been the public activity center of Venice's political, religious and traditional festivals. After Napoleon occupied Venice in 1797, he coveted the scenery here and praised that St. Mark's Square was "the most beautiful square in the world". Therefore, he ordered the governor's palace near the square to be changed into a palace. Today, people still call it Napoleon's Palace. St. Mark's Square is the main scene of the carnival every year, but it is always lively like a stage, never cold. The crowd here is like a tide. There are countless pigeons flying off and on the square, and tourists live with them peacefully.

Looking at the sea, the rows of gondolas are very beautiful. Looking at the winged lion again, it seems that he is proud to be admired by tourists.

A piece of tide is like a huge mirror on the square, which makes all the buildings look more exquisite and shiny, embedded in the middle of crystal or glass. In addition to the outdoor furnishings of the surrounding cafes and the colorful clothes of tourists, it forms an extremely fascinating picture. On the square, mothers and children played in the water, and young people took off their shoes and socks and ran back and forth; Large groups of pigeons, sometimes flocking to the ground to look for food, sometimes with the sound of flapping wings, flew all over the square.
