How do peonies and lotus flowers hang in the genealogy?

Genealogy is a special document in the form of genealogy, which records the genealogical reproduction of a family and the deeds of important people. Peony and lotus are two different plants with different meanings.

Peony is the head of a hundred flowers, the king of flowers, rich and gorgeous, symbolizing that men hang in the East. The lotus leaves the mud but not stained, clear but not demon, symbolizing the woman hanging in the west.
