Schweizer said: Only those who are willing to seek to discover how to serve others are truly happy. How to achieve better service is what Central has been thinking about and doing - Central strives to do every detail of the work well through strict system construction, scientific process management, and flexible team operation. Then on the basis of controlling the details, we complete the work in time, solve the problem, and give feedback to the customer, which is our requirement for ourselves; when doing service, we take the customer's business as our own business, We communicate carefully and respect our customers as we respect ourselves. This is our requirement for ourselves; we operate legally and will not operate beyond the law for any reason, which is also our requirement for ourselves. We are doing business with heart.
