Except for product and technical satisfaction by customers, we have also established a comprehensive management system inside company with customer satisfaction as the leading principle. All internal management has to follow the standard of customer satisfaction. In terms of product sales and marketing, we also established a quick reaction system so that all customer needs can be serviced on time. As part of effort, we introduced ERP management system, so that an accurate and on time management is carried out throughout the process of internal management.
