Note: While ensuring quality, we must also control the production speed and try to ensure that each customer receives the best quality product in the shortest possible time. When ensuring pre-sales service, we should also pay attention to tracking the quality of after-sales services, and ask customers for feedback at any time. If customers encounter any problems with technology or use, they should provide voice or video help as soon as possible.
