One Rule Worth Keeping
If you remember only one thing, let it be this: data is more reliable than experience. Around connector care this holds in most situations, because many people do the opposite and the gap between the two approaches shows clearly over time.
How To Respond On Site
If a connector issue appears, stop using it and keep the site, contact the responsible party, then keep a record. Order matters: clear records make later review far quicker and keep the next shift informed about what actually happened there.
Local Rollout Choices
In Yantai we start with a sample and a smooth process before widening coverage. We would rather take fewer jobs than leave current service under-supported, because a steady response matters more than a long list of signed sites.
Connector care cost usually splits into a time-varying part and a service part. Publishing both separately builds trust, while exact ranges follow on-site measurement rather than a generic public number that may mislead users about their own case. Good care is less about effort and more about timing, because a short check done at the right moment prevents the long, costly repair that a neglected connector eventually forces on both the owner and the service team.
