What is the name of the festivity in Peru where the people dance around a tree adorned with gifts?

if possible, i would also like to know where i can get images of it

its called yunza, they adorn the tree with gifts and they chant around it hitting it with an ax as they dance around it. After the tree falls everyone jumps in and takes a gift, some gift bags have money and some have simple toys. But the person that chops the tree down has to put on up for the following year. Also there is a lot of Peruvian folklore music and dancing. Also a show of the "scissors dance" where a person dressed in folklore clothing dances with scissors. Its pretty cool.

I know this cuz I'm Peruvian and my dads friend is from the area from Peru where they celebrate this. They do it every year i think also the i think they serve guinea pig delicacy

It is named YUNZA. It is a kind of communal party, lots of gifts and fun!

Peruvian wife from selva has never heard the term yunza. They just call it carnaval. They put up a tree tied with lots of stuff...gifts...at top. On last day of carnaval they dance around it and wack at it with a machete until they cut it down. The tree....umbisha.....falls (normally guided safely) and people scramble for the gifts. I have been to 2 carnavals and have never heard the term yunza used.
