Protest is not allowed in China, but people protest in many ways in China: suicide such as self-immolation, throw posters…..and naked..
Zhang Quan lost four family members in a car accident, but received no compensation. He protested this way:
naked in Tiananmen Square on July 4th, 2012. He was arrested and jailed for five days in Beijing, then detained in his hometown – Ruyang, Henan. Most likely, Zhang will be sent to labor camp for at least a year.
