Westing Bridge LL is a family-owned business that was started by four Zheng brothers. ChiaoGoo needles are designed and distributed in Troy, Michigan. The manufacturing facility is based in Hangzhou, China. Demand for the needles originated with Mama Zheng. She is an excellent knitter and knit in order to keep her family warm during the long, cold winters. Mama Zheng would often knit extra items and sell them to neighbors and friends to make some extra money for her family of seven. She was the needle “tester” and frequently asked for special needles to meet her needs. Mama Zheng is the inspiration for the ChiaoGoo brand name which means “highly skillful and crafty lady”.
