Is turtle yang heavy?

In Wang Wen's gossip, the tortoise's five elements belong to fire, and its image represents: flame, heat, sun and yang.

Scholars in China like to raise turtles most, because their patterns are mysterious.

Tortoise pattern on the back: there are three squares in the middle, representing the "three talents" of heaven and earth. There are ten squares around Sancai, representing "working for ten days". Tortoise pattern at the bottom: there are twelve squares, representing "Twelve Earthly Branches".
