“Unlike many companies that simply import products from China and rebrand them, this is a firm that truly engages in engineering, production, development, and value creation. With the products they have developed, they have freed us from dependence on foreign technologies. We hope that you will continue to build on this success with the same dedication and determination, and represent our country proudly around the world under the motto of being “local and national.”
