2. The significance of ginkgo tree
Ginkgo trees are called "living fossils". At present, many ginkgo trees in China are over 5,000 years old. In nature, ginkgo tree is the longest-lived creature. What's even more peculiar is that Ginkgo biloba, as a tree species, has remained unchanged for more than 200 million years. The dinosaurs of the same generation have long been extinct, but Ginkgo biloba is still full of vitality. Ginkgo tree is a national first-class protected plant.
