What are the customs when Americans die?

There are many funerals. Didn't you see a large crowd mourning for a cross on TV? But they are all cremated first and then buried, just because the United States has enough land to be buried alone, unlike a cemetery in China where there are tens of thousands of people.

In recent years, sea burial (ashes scattered in the sea) and tree burial (ashes buried under a tree, metaphor or contribution) are more popular.
