"User first" emphasizes that the user is always put first, and the user is above and above everything else. "Service with heart" emphasizes the basic principles to be followed in the service. Customer satisfaction is our work standard, and we are to create touch with our sincerity. To serve with heart, one must be "sincere" and "sincere", that is, service must start with heart-to-heart communication. Second, we must be "hearted" and "enthusiastic", that is, devote all our efforts and energy to serve users wholeheartedly, and consider them wholeheartedly. Third, we must be "attentive" and "patient". High-quality service means starting from small things, that is, seeing the truth in the subtleties, and persisting in seeing the kung fu for a long time. Take the trouble and be patient until the user is satisfied.
