I see the current Chinese lockdown as the ultimate "never ever lose face, no matter how high the cost" scenario. China decided very early on to solely allow their vaccines (which turned out to be pretty low quality) and to combine that with a rigorous containment policy.
The idea of a containment policy was pretty solid and effective (even though the measures taken were sometimes beyond all reasonability), the problem was that the low vaccine efficiency completely imploded that idea with the Omicron mutants.
And now, the Chinese government is in a pretty bad place politically... their choices are a) to admit that the vaccines are shit, allow internationally recognized vaccines and keep containment policy until these have been rolled out b) admit that the containment policy has failed and accept the spread of covid like most Western countries did or c) counteract the improved spreadability and immuno-escape capabilities of SARS-CoV-2 by harsher containment measures.
Neither of these three options are good, and I believe that the fear of Xi's regime to "lose face" will inevitably lead them to option c) as it is the only way that does not force the regime to admit that their decisions have been faulty - the central committee can simply declare lower ranks not following orders are the culprits and so Xi's face is saved.
There is also an addendum - as all three options lead to a severe hit in popularity and correspondingly a threat of the stability of the Chinese government, the regime may decide to invade Taiwan for political gains ("we led the secessionists back into the homeland"). The key question there is if the regime is willing to risk a Russian scale defeat, as unlike Russia China has practically zero experience in military conflict and Taiwan has a direct bilateral defense agreement with the US.
