捷克采购需求：中国市场，柯桥市场

I hope you're doing well. My colleague is currently exploring the Keqiao textile market and is specifically searching for quality sofa fabric. Do you have any recommendations for shops that they should visit before their departure? If possible, please share the location or shop numbers of those recommended places. Your assistance would be greatly appreciated, as it will help enhance their shopping experience. Thanks in advance for your help!
