Chinese protesters have turned to blank sheets of paper to express their anger over COVID-19 restrictions in a rare, widespread outpouring of public dissent that has gone beyond social media to some of China's streets and top universities.
Images and videos circulated online showed students at universities in cities including Nanjing and Beijing holding up blank sheets of paper in silent protest, a tactic used in part to evade censorship or arrest.
China is adhering to its tough "COVID zero" policy even while much of the world tries to coexist with the coronavirus.
