There is a tree by the roadside, which smells delicious and has small white flowers. Does anyone know what kind of tree this is?

Cinnamomum camphora is an evergreen tall tree, which is rich in aromatic substances. Camphor is extracted from camphor tree. The "fruit" of Cinnamomum camphora is black and round when it matures, such as the size of mung beans. It has high oil content and can be used to extract oil. Cinnamomum camphora oil is edible and tastes cool and fragrant. Now is the season when camphor trees are in full bloom, and you can smell the fragrance of camphor trees from afar. Cinnamomum camphora, with pale yellow leucorrhea and clusters of flowers, is very small, about half a grain of rice. Its "fortune telling" is not good.
