Citizens in various districts of Shanghai rebelled against the lockdown in the form of balcony concerts, projections, etc. The form of protest of banging pots and pans originated in Latin America and has since spread to the world, especially in developing regions. During the more than two months of lockdown in Shanghai, balcony concerts dominated by pot knocking continued, especially in areas where supplies were scarce, such as the Baoshan residents organized pot knocking in early April. On April 28, huge pot knocking protests were held in all districts of the city.
