Layer-by-layer checks on product quality
High standards and requirements for services. Provide customers with the information they need in a timely and fast manner, and always prepare part of the commonly used product information.
In the process of product sales, customers have unsatisfactory aspects or feel inappropriate problems, which should be dealt with in time.
After the product is sold, the quality of the product will not change dramatically in a short period of time, and the service requirements of customers in the later period should be met in time.
