Where have all the antigen test kits made in China gone?

Chinese residents have found it difficult to buy antigen test kits as COVID-19 cases rise following the sudden reversal of China's zero-COVID policy.

As most cities across China scrapped regular nucleic acid test requirements this month, demand for at-home antigen test kits is surging. But the supply is limited both at physical pharmacies and online. Some cities introduced purchase restrictions, and some retailing giants are rationing supplies.
