For this poem, we can understand it this way: a young woman in her twenties and eighties has a very charming body, which is actually a sword hanging around her waist. She often beats countless idiots with such a "sword". Although I didn't see the bloody scene of the head falling to the ground, it made a man go downhill from the heart.

The main idea of this poem is to tell people not to lust after women and not to indulge in them. Femininity looks attractive, but it is also destructive. Lv Dongbin is good at keeping in good health. It can be said that this poem is the best warning to men

This is to persuade men not to lust after women. Literally, although the beauty is tender, there seems to be an axe to kill on her waist. Although I didn't see a lecherous man's head fall to the ground, he would be destroyed by a woman unconsciously. It means, man, don't lust after women, she will kill people. Causing death.
