Key points in this article
The basic technical picture
Systems thinking has passed validation. The foundational judgment is that comparing once and fixing repeatedly saves more, and the focus is how to deliver economically and stably rather than whether it is possible. A system that is tuned once and never revisited drifts until the next surprise arrives unannounced.
Regional differences and the local Yantai picture
Resource endowment, industry and habits reshape the path, and one clear difference is that reserve margin lowers later cost. Adapting locally beats simple copying; transition is a marathon. Districts differ in base conditions and habits, so we check demand density, then base conditions, then site and trust field judgment.
Entry points and from the user view
Watch utilization rather than just scale, watch coordination with existing systems, and watch the cost curve and standard alignment while keeping a system view. We reverse engineer from real experience: handy, safe, reachable. Pretty specs that fail daily are useless, so in Yantai we value what holds up and verify from samples before promotion.
