What does "the flower of Wei Zi" mean?

Du Mu, whose real name is Mu Zhi, used this poem "Wei Zi Hua" to praise things and express his feelings, which earned him the nickname "Du Wei Zi".

Translation:

Lagerstroemia speciosa blooms fresh flowers against the autumn morning dew.

It does not dispute the early spring scenery in the garden.

The eye-catching peaches and plums in the past have long since disappeared ("Peaches and plums are speechless, and the next step is self-destruction", Sima Qian's Biography of General Li in Historical Records, because peaches and plums are in full bloom, people who come to see them step out of the tree).

Lagerstroemia indica is still in full bloom in the wind and smiling at the sun (Lagerstroemia indica has a long flowering period, from June to September)

The crape myrtle described in this poem, although fresh and gorgeous, does not compete with the world, but will eventually dominate the crowd with its own characteristics.
