Pan Lu Deng Xiaoxian, in ancient books, uses five conditions to describe men "being exhausted."

Currently, it refers to the five main qualities that attract women in men,
or the five conditions men need to meet to pursue women.
It means being as handsome as Pan An,
having the sexual prowess of a donkey,
being as wealthy as the Han Dynasty tycoon Deng Tong,
and also being careful and gentle in caring for women,
being considerate and attentive to them,
and men who have more time to spend with women.
