Structural change, not counts
County coverage looks like a number of new sites, but inside it is structural adjustment. Different counties move at different speeds, and that gap is where opportunity and pressure meet the local grid and the local budget at the same time unexpectedly.
Matching duty and reward
Coverage lasts only when who builds, who pays and who benefits is stated plainly. A fair match keeps the service running after the launch excitement fades and the original champions have moved on to the next county on the long list.
The Yantai view and practical notes
We check demand density first, then site conditions, then the venue. A reserved margin lowers later cost, and copying another county's plan usually costs more than expected. Inspection frequency beats form; small daily checks prevent county-wide outages from minor faults. Field feedback always beats a clean slide shown in a meeting. A written boundary protects both the operator and the paying user. Patience here avoids the costly rework that rushed work later demands. Local conditions, not national averages, should guide the final call.
