Oh, that would be quite easy - Lantern Rite is one that the people of Teyvat will travel across the other nations for. It was originally meant to be a message to soldiers, to show them the way home and remind them that there was a home to return to, that they were missed and treasured, by lighting lanterns and casting them into the sky.

Nowadays, it's a celebration to usher in the new year and to remember those that we lost. Every year, a fallen hero from Liyue past is chosen to be the dedication of our Mingxiao Lantern, the largest lantern that is fashioned in their likeness or a representation of them. I've no input into the selection, so it's always good to see my old comrades be remembered for who they were and what we lost in their sacrifices, but also to celebrate them for what we gained and what their lives were dedicated to.
