Metasequoia.

In 1943, Professor Wang War, a botanist in China, discovered three large trees of extraordinary appearance in Knife Creek, Wanxian County, Sichuan Province. It was not until 1946 that it was confirmed that the trees were water fir, a plant that had lived on Earth hundreds of millions of years earlier. Until then, scientists had found fossils of them only in ancient formations, arguing that water fir had long since been extinct on Earth. The discovery has caused a stir around the world, with water fir being called a "living fossil" of the plant world.

is a tall deciduous tree, belonging to the genus fir. Its trunk is tall, its branches are horizontal, and the whole tree is pagoda-shaped. The leaves are flat, slightly needle-shaped, feathery, and flexible and flowing. It spring and summer green, golden after autumn, early winter brown red, beautiful abnormal. The flower monogene of the water fir, male and female, after being powdered to produce a near-circular ball fruit, seed inverted egg shape, winged.

water fir tree-shaped, adaptable, fast-growing, is an excellent ornamental and green tree species. Its material is thin and soft, can be used in architecture, life, paper and many other aspects. A large number of water fires have been planted all over China, and more than 50 countries and more than 100 research units abroad have successfully introduced water fir.Among the water fir found in China, the largest are two 46-meter-high water fir in Lota Township, Longshan County, Hunan Province, with a chest circumference of 4 meters and a 3.7-meter tree, about 300 years old.

well-known living fossil plants in China are vultures, silver fir, water pine, Taiwan fir, money pine and so on.
