In the end, the Narrator and Luo, are still, left on the Phoenix of the Sky.
Only now, it is without the Little Seamstress.
A few days before her unexpected departure from their lives, they notice only one thing that could have possible alerted them of it. A change in her wardrobe. Losing the look of a mountain-girl and instead getting a new outfit that fit more with that of a city goer, the Little Seamstress completed her
change into an 'intellectual'.
At last, the fruits of Luo's labors had bloomed, even if he hadn't grasped all their meanings yet.
The Little Seamstress left for the city.
She never told anyone until it was too late to stop her. On the morning of her departure, her father, the tailor came into their village while they were working in the fields. Upon hearing of her leaving, Luo and the narrator both ran after her.
When they finally catch up, she leaves them with
the one thing she'd learned from Balzac"A woman's beauty is a treasure beyond price"
