Monks from Shaolin Temple sat on the ground during a 'No Cellphone' event at an office building in Zhengzhou, central China's Henan province on Aug 25, 2015. They encouraged white collar workers to put down their cellphones and place them in a box from 10:00-18:00 in exchange for free tickets to a Shaolin concert. However, nobody took up the invitation.
