There were so many volunteers to help in thousands of people but excluding them twenty of us volunteered in our own field independently. We helped people search seats and attend the sacred dances comfortably, we helped to keep the ground clean, made sure to be there to control crowd and made sure there don't be any quarrel or fights among the citizens. We also helped to guide some tourist and old citizens without proper guardian to receive blessings and all. We were on service for 4days and 8 hours per day. 20*4*8=640
