2011年11月28号我公司在潍坊恒信建设集团成功召开产品推介会，此次推介会的顺利召开让我公司与潍坊恒信建设集团建立了良好的合作关系，同时也为我公司的玻纤复合门窗进入潍坊市场奠定了好的基础。

On November 28, 2011, our company successfully held a product promotion meeting in Weifang Hengxin Construction Group. The successful holding of the promotion meeting allowed our company to establish a good cooperative relationship with Weifang Hengxin Construction Group, and also laid a good foundation for our company's glass fiber composite doors and Windows to enter the Weifang market.
