The china presumed missing 200000000 girls killed during the one child policy, seem to be alive and well - they were just hidden from the records IIRC. So china may have more labor than official statistics say. And the one child parents now are wanting grandkids from said one children. Lots of them and fast. China demographics will improve.

They also figured shanghai tower and aircraft carriers and their first commercial airplane hull while being busy with ballpens. Shanghai auto expo also showed a lot of new hybrids, all electric domestic brands and models.

I think they will be fine.
