Why do green hotels use ginkgo leaves as a symbol?

"Ginkgo biloba is a plant with high medicinal value. Ginkgo biloba is an ancient tree species in China. This is a magical medical tree. When Jurassic dinosaurs took control of the earth more than 250 million years ago, Ginkgo biloba was already one of the most prosperous plants. Life on the earth has undergone hundreds of billions of years of changes, especially after being covered by glaciers in the fourth century. Only Ginkgo biloba remains the most primitive appearance, and is called the "living fossil" in the history of biological evolution. -Excerpted from Baidu Encyclopedia

"The guiding ideology of green hotels: take environmental friendliness as the concept, integrate environmental friendly behaviors and environmental management into hotel management, implement the purposes of environmental protection, economy, health and safety, adhere to green management and resource conservation, build green consumption hotels, protect the ecological environment and make rational use of resources." -Excerpted from Baidu Encyclopedia

Personally, Ginkgo biloba has a strong representation in plants, and is rich in historical origins and environmental protection implications endowed by nature, so it has become the symbol of green hotels in China.
