What are the possible benefits of the Chinese government continuing to pursue a zero covid policy?

China seems to had done really well during the pandemic and has had far lower deaths than Europe and United states.

However as countries around the world vaccinate their population and learn to live with covid, China seems determined to pursue a zero covid policy.

What political motivation is there for this? In many places death rates have not increased despite the infection rates being out of control. What would be the long term goal of zero covid since covid is unlikely to go away?
