chairman speech


Winjoy (or wei jing in pinyin), is taken from an important ancient scripture the Book of Documents (shangshu). “Only through careful observation and persistent concentration can we stick to an impartial and correct path.” Therefore, Winjoy will adhere to this motto, strive to build the most reliable professional provider of high-performance copper alloy strips with our craftsmanship and dedication.

The mission of Winjoy was defined as “Dream, love and the world; Excellence, unity and strong foundation.”, which is the result of the original intention of Winjoy’s establishment-- to “gather a group of people with dreams to do something for China's copper processing industry”. As several founding team members and I have been working in this industry for nearly 30 years, we are deeply aware of the gap between China’s copper processing level and the world’s advanced level. With the sense of responsibility for our nation and our love for this career, all Winjoy people will be passionate and never stop doing what we love. !
