7 in 12k is way less than the rate you'd expect in the overall population. It's 0.5 in 1000 people. The US' overall death rate was 8.8 per 1000 in 2020.
And that's before taking into account the fact that this will be an underestimation since deaths tend to trail the infection count by something like 2 weeks.
Still more alarming than ridiculous in my books.
People die all the time. Every day. Shanghai has 25M people. Let's assume the US's annual death rate of 8.8 per 1000. That's 220k deaths per year, or 4230 deaths per week.
Statistically with the current numbers, getting everybody infected would result in less deaths than having no covid at all :o) Sure, we'll only see real deaths with a delay of a few weeks, so that's witless, but as stated in my sibling comment in this thread, Omicron seems not to deliver on this from my personal experiences at all.
Having a total lock-down over it seems absolutely ridiculous to me.
But I am worried about the effectiveness of their vaccines and the rate at which the disease will eventually spread.
