What is Mao Mao where the buttonwood fell? Mao Mao introduced it.

1. The "Mao Mao" floating down from the buttonwood tree is called floating catkins. In fact, when the buttonwood tree germinated, the seed balls of the previous year began to be sown, and when the fruit balls burst, floating flocs would fly out. This "Mao Mao" is the hair on their fruit. These fruit hairs are the seeds of the French phoenix tree.

2. Every year in late spring and early summer, when the fruit is ripe, these fruit hairs fall with the wind like dandelion seeds.
