Lagerstroemia angustifolia is a type of carpentry belonging to Group I of Vietnam
Unlike other brothers with other mausoleums, which only belong to group III, Bang Lang Beaded has beautiful woods, the pattern bends like clouds, even the grain is slightly sparkling when there is direct light. The tree grows very slowly, leaves are small, flowers are very beautiful and there are many colors from pink to pink and white, the shape of Tuong vy flowers (but the size is much larger) than other species of lager species. This species is distributed in Cambodge, Laos, Thailand and Vietnam. The current status in Vietnam is very small, not only because of the rare woods, but also because of the beauty of flowers, even the remaining stunted tree stumps are excavated and brought back to make trees.
