This festival is in April of Gregorian calendar 1 year, which is a popular folk festival in the west since19th century, and has not been recognized as a legal festival by any country. On this day, people cheat and play tricks on each other in various ways, and often at the end of the joke, they will expose and announce that the object of the joke is a "fool".
