What brand is Shan Yu cashmere?

First-line brands have a good reputation for cashmere, and three cashmere brand conferences are held every year to reach the standard and become a first-line brand. Cashmere is a thin layer of fine hair that grows on the outer cortex of goats and covers the roots of goat coarse hair. It grows to resist the cold when the sunshine time decreases (autumnal equinox), and falls off when the sunshine time increases (vernal equinox).
