There’s a detail worth mentioning about this round of typhoon prevention: Shanghai requires a “timely and decisive” shutdown of schools, suspension of work, and closure of businesses; in Hangzhou, the entire city suspends classes in an orderly manner; in Wenzhou, it goes straight to the “five suspensions.” In Zhejiang, all 14,828 ocean fishing vessels return to port to seek shelter, 1,906 marine aquaculture workers are evacuated to shore, and Ningbo Airport cancels all flights throughout the day for nine days.

Each time a typhoon comes, a certain kind of sound shows up: “Classes are cancelled, but the wind isn’t even that strong.”

This account shouldn’t be算 like that. The costs of shutting schools and suspending work are definite and computable—production value lost per day, and classes lost per day. The costs of not shutting down are probabilistic, but once something happens, it’s irreversible. The two sides are fundamentally asymmetrical, so the rational approach in the first place is: “It’s better to cancel and be wrong than to risk it.”

The Zhejiang governor’s exact words are: “Based on the most unfavorable scenario, make the most thorough preparations.” Translated, that means: allowing yourself to look like you overreact in hindsight.

Whether an organization dares to make decisions like that actually says a lot about its level. Did yours get shut down over there?
