The implication of porch elephants and ginkgo leaves

These two meanings are good luck, strength, wisdom, protection and longevity.

In many cultures, porch elephants are regarded as symbols of good luck, strength and wisdom. In geomantic omen, putting elephants at the entrance is considered to attract positive energy and protect families from evil. Elephants are also regarded as a symbol of longevity and happiness, so placing elephants on the porch can bring positive energy and good luck.

Ginkgo biloba is a symbol of autumn. Ginkgo biloba is an evergreen tree whose leaves turn golden in autumn, so it is regarded as a symbol of life cycle and change. Ginkgo biloba leaves are also considered to have the meaning of longevity and happiness, because ginkgo trees can grow for hundreds of years and are described in ancient legends as places where immortals often stop.
