The Tomatina Festival（西红柿节）is a festival that is held in a town named Bunol in Spain, on which people throw tomatoes for fun. It is held on the last Wednesday of August each year.
In 1945, during a parade（游行） in the town one day, young men who wanted to be in the parade started a fight in the town square. They used tomatoes as weapons（武器）. This is the most popular story about how the Tomatina Festival started.
At around 10:00 am on Wednesday, activities that are organized to celebrate the festival begin. The first one is climbing a pole with a ham on top. When a person is climbing, some people sing and dance. When the person drops the ham off the pole, the tomato fight starts. The tomatoes come from Extremadura. The tomatoes there are less expensive and are grown specially for the festival. The number of tomatoes used is about 150, 000. After exactly one hour, the fight ends. The whole square becomes red because there is tomato juice everywhere. Then hoses（水龙带） are used to clean the square and to wash away the tomato juice on people's bodies. After that, the town goes back to the way it was.
The local government has made some rules for the safety of people. One of them is as follows: People have to squash（把……挤软） the tomatoes before throwing in order not to hurt other people.
The Tomatina Festival has inspired other similar celebrations in other parts of the world, for example, in the city of Dongguan, Guangdong Province, China, a tomato fight is held on October 19th.
