What kind of acquisition are you talking about? Are you a herdsman or a manufacturer or something? From the source, there are herders raising sheep in Inner Mongolia and Outer Mongolia, Ningxia and Liaoning. Every April-May, the cashmere factory will go to the herdsmen to collect cashmere and then prepare to sell it. As for the sales method, it depends on the operation mode of each factory. Now foreigners have learned a lot and come to China to collect cashmere directly in cash. That's about it.
As far as I know, my answers are Chifeng City in Inner Mongolia and Qinghe County in Hebei Province.
