Venice's glory can not be separated from the 41st Governor Dandolo. When he became governor, he was 86 years old, blind and hard of hearing, and had a few days to live. During the Fourth Crusade, which began in October 1204, he offered the Crusaders maritime and logistical support at a price of 8.5W Marko gold coins. Originally the sword of the Crusade meant that Jerusalem was going to expel pagans and liberate the Holy Land. As a result, Constantinople, the headquarters of the same Orthodox Church, was looted. Dandoro not only took back the labor fees, but also partitioned three-eighths of the territory of the Eastern Roman Empire. He established the monopoly position of trade and Commerce in the Eastern Mediterranean and became the biggest winner. In ancient Rome, such achievements were to be triumphant. But Dandoro, 98, did not see the cheering crowd dying in Constantinople and buried in St. Sophia's Cathedral. His son, Tonil, has always been Dandoro's deputy, helping the elderly governor to handle government affairs, both in peacetime and in wartime. So the people called on him to become governor, and even hoped that he would simply start a Dandoro dynasty. Tony refused the people's request and went out to do business. Later, there was a war between Venice and Genoa, and Tony died in a fierce battle. More than 800 years ago, Laozi was a hero.
