His nickname? “Superman” because his backpack is adorned with the superhero acronym. On Chinese social media, the citizen has become popular in recent days due to his activism against the zero covid policy of the authorities.

At the door of an apartment complex in Chongqing, southern China, this man in his thirties is talking to his neighbors who have gathered to demonstrate after months of restrictions: “If I get this disease, I guarantee recovery in seven days. Messi had Covid, Ronaldo had Covid, tennis player Djokovic had Covid twice and won Grand Slams. And if the impact of Covid was significant, they would have been retired a long time ago.”
