what kind of tree is it?

Hello, this is acacia, and there is a sad legend about acacia.

Husband is a leaf, I am a flower, flowers are not old, leaves do not fall, life is different, the world is happy!

This acacia is the first tree to complain. It doesn't bloom. According to legend, there was a scholar who studied hard for ten years at a cold window and prepared to go to Beijing to catch the exam. When he left, his wife pointed to the tree in front of the window and said to him, "Husband, if you are here, you can go to high school. It's just chaos in Beijing, don't forget the way home! " The scholar promised to leave, but he was never heard from again. Fans are waiting at home, waiting and waiting, their hair turns white, and they haven't waited for their husband's figure. When the end of life is coming, the pink fan dragged her weak body and struggled to the bitter tree that confirmed her and her husband's vows. She made a heavy oath with her life: "If her husband changes his mind, let this bitter blossom from now on. My husband is a leaf and I am a flower. Flowers never grow old, but leaves never fall. I have different hearts all my life, and I will be happy all my life! " Then he swallowed his last breath. The next year, all the bitter trees really blossomed, soft and pink, like handfuls of small fans hanging on the branches, with a faint fragrance, but the flowering period was very short, only one day. Moreover, since then, all the leaves have actually opened and closed in the morning with the flowers blooming and falling. To commemorate the infatuation of fans, people renamed the bitter tree acacia. This story makes people feel that this acacia tree has suffered too much under the reputation of joy, which makes people feel particularly sad. I think all the beauty in this world is actually the image of a beautiful soul supporting people's beautiful vision and hope.
