Food shortages in *China* are highly likely as a result - remember, quarantines are supposed to be absolute, no farmer is going to be delivering fresh food from outside the quarantine zone. Even in China, food is delivered in a Just In Time plan.
Hope the Chinese have huge stockpiles of air droppable rations; they may need them.
A quarantine of the city will get ugly fast. The worst case is very bad... however now that it's happened we can pray that it will blow over quickly, somehow...
The angle about Xi and the digital currency/social credit is intriguing and unfortunate...
