Where are the three tribal boxes of the inaugural battle song?

The specific locations of the three tribal boxes of the inaugural battle song are as follows:

1, the first box is in the big chief's tent, and there is a coordinate next to the bonfire on the left hand side of the door.

The second box is in the stable, under the second white horse. Because the box is small, it may be blocked by the model of the horse, so it can't be ordered. Just count it a few times, or the horse will be gone.

The third box is in the forest. Looking for the original tree. There are two white rabbits jumping nearby.
