The four ancient trees in China are?
Toona sinensis: In ancient times, there was a Toona sinensis, which took 8,000 years as spring and 8,000 years as autumn, so it would not die. There was a spring under it, so it was immortal.
Ruomu: South China Sea, between black water and blue water, has the name Ruomu. If the water comes out, it is called in.
Fusang: In the East, there are places where Fusang, Fusang, Damu and Sun live.
Building wood in the sky: there are trees in the middle, green leaves and purple stems, mysterious and yellow. It's called building wood. There are no branches. There are nine buds and nine gourds below. In fact, it is like hemp, its leaves are like awns, and the Yellow Emperor did it, connecting the four poles of heaven and earth and reaching heaven and earth.
Cinnamomum camphora contains terpenoids bicyclic hydrocarbons, camphenes, limonene, eugenol and other chemicals. These substances are organic substances with fragrance, so Cinnamomum camphora has fragrance.
Cinnamomum camphora is a subtropical tree species, mainly distributed in the south of the Yangtze River, and it is an evergreen tall tree of Catalpa in Lauraceae. Flowers in early summer, yellow-green, panicle, broad crown, lush foliage, shady everywhere, magnificent momentum, is an excellent street tree and shade tree. Cinnamomum camphora has the characteristics of temperature resistance, corrosion resistance and insect repellent because of its special aroma and volatile oil. It is an ideal wood for making expensive furniture, high-grade buildings, shipbuilding and sculpture. Camphor for daily use is a white crystal extracted from the roots, stems, branches and leaves of camphor tree. It has a cool fragrance and is used to prevent moth. It is also widely used in medicine and chemical industry.
Cinnamomum camphora is very distinctive, its bark is rough, but its texture is very uniform, and there has never been mottled poplar or tumor of willow. The branch is divided into two and two into four. They won't cut corners or gild the lily. The crown is spherical in shape, drawing a beautiful curve in the sky. Zhangshu is the calligraphy of Dongpo, Su Like. Round and continuous, handsome and elegant, but quite satisfactory. If it is a hillside full of camphor trees, it is simply a peerless monument of Su Dongpo. Therefore, people who study art like to use camphor tree as the object of sketch. What is even more rare is that camphor tree has a special fragrance, which can repel insects, and gardeners hardly need to spray pesticides. These two days in Jiangxi, which is famous for its camphor trees, I feasted my eyes, which greatly satisfied my special hobby of lack of human nature. There are camphor trees everywhere in Jiangxi, and there are many old trees over 500 to 600 years old, scattered in villages, rivers and hilltops.
