full life cycle, full process service

What kind of service is the best service we can give our customers?  

The implementation of "full life cycle" services to further improve the service level is the direction of our efforts.  Before customers buy products, we always patiently and carefully introduce the details of the products for customers, so that customers can buy the most needed products. After customers buy products, we   always solve all kinds of problems that customers encounter in the first time. this is full process service.
