Lagerstroemia indica is produced in southern Asia and northern Australia, and distributed in East China, Central China, South China and Southwest China. Wei Zi each flower has six petals, just like a roulette wheel. When it blooms, the trees are full of beautiful flowers, so Wei Zi is also called "full house".

Lagerstroemia indica has beautiful flowers and smooth trunk. The trunk of young Lagerstroemia indica grows epidermis every year and falls off by itself every year, making the trunk look fresh and smooth; The adult Lagerstroemia speciosa has peeled off its skin and looks bare. It is said that even monkeys are too smooth to climb, so Lagerstroemia speciosa is also called "monkey thorn".

If you gently touch the bare trunk of Lagerstroemia indica with your hand, its top branches will shake gently at once. The branches shook their leaves and trembled all over, just like a person being scratched under his arm. It seems that Wei Zi is really "ticklish", so she is called "ticklish tree".
