Experience of more than twenty years in different positions offered me opportunities to understand different job aspects.As a technician、director(in Tontru), I learned how important it is tocooperate, and how to spirit up employees.As a P.C. & buyer, I have learned how important it is to provide the manufacture relative goods on time, on qty’ and quality. All the experience as P.C & SE makes me confident with checking vouchers, controlling the stock, and developing suppliers, managing vendors. The same time developed the technique of selling and service, when improving the ability of making plan of production & purchase. The most important things are communication and cooperation for me.Specialties: Union negotiation, purchasing, suppliers sorting, price communication, inventory control, MRP、MRPII、ERP knowledge.
