I have a bronze turtle, which is chinemys reevesii's little turtle. The big turtle at the bottom is on a wavy flower, and its shell has copper coin texture. What does this mean?

This is a bronze version of the work, carved with seawater, with a big turtle carrying a small turtle on its back. Sea water symbolizes the blessing of the sea and the longevity of the mountain. Turtles are aquatic animals, characterized by hard armor on the abdomen and back, hunger and thirst tolerance and long life. Use a big turtle with a small turtle on its back to describe longevity. The copper coin pattern also means auspiciousness.
