Is the smell of Chinese girls' feet related to their geographical location?

I've heard that the smell of northern girls' feet is different from that of southern girls.

Northern girls' feet are said to have a slightly pungent, leathery odor, generally uncomplicated, 

like the warm, calming scent of fermented leaves in a misty forest after rain. 

Southern girls' feet, on the other hand, are generally more acidic, with a complex and rich pheromone scent. 

The flavor of southern girls' feet is more palatable, with a brighter, cleaner acidity, a floral-fruity top note, 

a tropical fruity tartness in the middle, and a subtle sweetness in the base note. 

I rarely smell insoles with a floral-fruity scent from northern girls; 

if I do, it's only a hint at the very end. Of course, there are exceptions, such as the faint glutinous rice smell of girls from the eastern part of the north. 

Everyone's perception of feet is different, so the conclusions will also differ. 

I form my overall understanding of girls' feet based on three dimensions: color, aroma, and texture. 

Color observation stage: Tilt both feet to observe the width. 

Young feet have a light reddish hue on the soles, with the toes flowing smoothly from large to small; 

the toes are moist and glossy, with smooth edges, and the color gradually changes from the instep to the sole.
