During the four days of the Dionysia, men and women, young and old, dressed in red and green, dressed in colorful, singing and dancing, spring tide bursting into the street like a bank. Except for pharmacies, hospitals and bars, factories are shut down, shops are closed, and schools are closed. It can be said that "no one belongs to anyone, and no one can control who." It goes without saying that the rich have gold and jade ornaments. Even the poor have to dress up their clothes and hats to join in the fun, knocking on empty cans, and clanging the local people into the carnival. People forget about prosperity and poverty, forget about sorrow and troubles, forget about tension and fatigue, and only have joy and happiness. At this time, the whole country, regardless of high or low, regardless of race or skin color, all merged into the ocean of joy like blossoming waves of joy. This joyful atmosphere also infects travelers from foreign countries, and many foreigners can't help but melt into it.
