No, Not really.I said lockdowns *in* Guangzhou which this most certainly is. Banning transit effectively ends all economic activity. Baiyun is the largest district in Guangzhou. Plus; it's not just Guangzhou; it's all over urban China with random lockdowns which severely restrict business when all movement in or out is banned - you effectively turn China into 8 million different customs entities; each of which have their own laws on trade and migration (i.e., a patchwork of bans that always change and for which no one is able to predict with any certainty what will happen in the next few hours/days/weeks/months)
Most places that are locked down are specific compounds. the baiyun district is 3.9 mil people, it's the largest district but the city has around ~19 million people so effectively just 20% of the population have restricted movement. My relatives Guangzhou haven't had lock down at all.
Not sure where you got the 8 million from. But many of the places are not locking down for for 2-3 months like before.
Having millions of deaths would be even more damaging to the economy. Likely the govt is trying to see if they can handle a soft opening and adjusting accordingly.
