Dragon. Ancient Chinese writings
The character has an image of an animal with a big mouth, big teeth, a long body, and spines on its back.
In the regular script form, this animal form has been pressed into a square shape. And it can be said that the limbs are separated, but the enlarged mouth and teeth can still be seen. You can see the head, eyes, standing gt;, and the long body shape with thorns, the right side of the dragon character gt;. What is the true image of this animal? I don’t know now.
