In Chinese folklore, dragons have nine sons, each of which has distinctive characteristics. These are often carved into ancient buildings and containers. Here are a few examples:
Bi Xi looks like a turtle that always carries big stonework on his back. His image is usually seen in monasteries.
Chi Wen likes standing on a high spot and looking around. His image can be seen on highest parts of palaces.
Pu Lao is very small and likes yelling a lot. His image can be seen on bronze bells.
