what do the symbols say on the Han Dynasty Tile?

Tiles in that dynasty always has characters and animals on it.
The characters are always auspicious words and speeches wishing for a good and safe and sound future.
Animals are the representative of the gods or animals related to the gods. They were used to driving off the bad luck and guard the houses.

Thank you. Can you send me more information on the meaning of the various animals on the roofs of Badaling, China?
