In the view of Li Huiqing, assistant general manager of Hepu Power, differentiated competitive advantage is the key factor for enterprises to become bigger and stronger. It is reported that every product produced by Hepu Electric Power, technicians should consider the cost when designing. On the basis of meeting customers' requirements for product performance, we should break away from all previous design concepts, think about designing new products, optimize product structure, improve production technology, introduce advanced production lines and reduce manpower. Hepu Power has made great efforts to reduce costs, and it still needs to ensure quality.
