First achieve immortality, then cultivate immortality.

What is the greatest advantage of immortality? Xu Mu replied: No need to worry about retirement, living paycheck to paycheck every month, no need to earn a fortune, just pure carefree living! The courtesan of the brothel, delicate and graceful; the wine of Hulu Lane, fragrant and overflowing; a poem inscribed on the White Crane Tower, met with thunderous applause. Having experienced the splendor of the mortal world, he asked himself a question—since he had already achieved immortality, why not enjoy eternal happiness in the mortal realm? Night after night of revelry, drunken revelry and extravagance. Until, after twenty years, he finally became desensitized, feeling that the surrounding splendor was like an illusory dream, that mortal life was too short, too fragile to be broken at any moment. This year the flowers fall and their colors change, next year when the flowers bloom again, who will be there? I want to buy osmanthus blossoms and share wine, but it will never be like the carefree days of my youth. So he went up the mountain to cultivate immortality.
