2. China National Tree: Ginkgo biloba, which first appeared in the Carboniferous period 345 million years ago. Ginkgo biloba was widely distributed in Europe, Asia and America in the northern hemisphere, widely distributed in the northern hemisphere in Mesozoic and Jurassic, and began to decline in the late Cretaceous. Until 500,000 years ago, the Quaternary glacial movement occurred and the earth suddenly became cold. Most ginkgo plants are on the verge of extinction. They are extinct in most parts of Europe, North America and Asia. Only China has superior natural conditions, which have been miraculously preserved. Therefore, scientists call them "living fossils" and "pandas in the plant kingdom".
3. National bird of China: Red-crowned crane, a large wading bird living in swamp or shallow water, is often called "the God of Wetlands". It has nothing to do with pine trees growing in high mountains and hills. However, because the life span of red-crowned cranes is as long as 50~60 years, people often paint pine trees as a symbol of longevity. The red-crowned crane symbolizes happiness, auspiciousness, longevity and loyalty. It often appears in literary and artistic works of various countries. The State Forestry Administration of China reported the red-crowned crane as the only national bird candidate to the State Council.
4. China National Animal: Giant panda, which has lived on the earth for at least 8 million years, is known as "living fossil" and "national treasure of China", the image ambassador of WWF and the flagship species of biodiversity protection in the world.
