Explain who or what "Año Viejo" is and its significance.

"Año Viejo" is a traditional ritual in many Latin American countries, particularly in Ecuador, Colombia, Venezuela, and Panama, where a large effigy or figure representing the "Old Year" is created and then burned at midnight on New Year's Eve. The effigy is usually made of straw, old clothes, and other materials, and sometimes includes a mask to represent a specific person or character.

The burning of the "Año Viejo" symbolizes letting go of the past year's trials, tribulations, and negative energy, and making way for a fresh start in the new year. It is believed that by burning the effigy, people can rid themselves of bad luck and negative experiences, and make room for prosperity, good fortune, and new opportunities in the coming year.

In addition to burning the "Año Viejo," some people also write down their wishes, dreams, and goals for the new year and burn them along with the effigy, in the hope that they will come true in the coming year.

Overall, the tradition of "Año Viejo" is a symbolic way for people to release the past and embrace the future with optimism, hope, and positivity.
