Explain who or what "Ano Viejo" is and it's significance.

Ano Viejo, also known as Año Viejo or Año Viejo effigy, is a cultural tradition in various Latin American countries, particularly in Ecuador, Colombia, and some regions of Mexico and Venezuela. This tradition takes place on New Year's Eve and involves the creation and burning of life-sized effigies, made of cardboard, paper, wood or other materials, which represent the "old year." The effigies are often dressed with old clothes or decorated to resemble popular characters or public figures, symbolizing the end of the year and all the negative things that happened during that time.

The significance of the Ano Viejo tradition is to bid farewell to the past year and usher in the new year on a positive note. The burning of the effigies is believed to cleanse the environment of bad energy, ward off evil spirits, and get rid of negativity, thus promoting good luck and prosperity in the upcoming year. This ritual also serves as a way for people to express their feelings and frustrations about the year that has passed, making it a form of social catharsis.

In some areas, there is a tradition called "Viuda del Año Viejo" or "Widows of the Old Year" where men dress like women and pretend to be widows of the effigies, seeking to collect money as a humorous way to foster a sense of community and solidarity during the celebrations.

Overall, the Ano Viejo tradition is a symbolic and meaningful cultural event that brings people together in a shared experience of renewal and good fortune for the new year.
