What does it mean to take root under a velvet tree?

Rooting under the osmanthus tree is to settle down under the osmanthus tree, or to grow under the osmanthus tree, never to move, and always to grow under the osmanthus tree.

Roots are also rooted in the soil under osmanthus trees, and they absorb the nutrients in this land together with osmanthus trees. Grow up together, together. Never leave.
