A religious group has a vow of poverty. They have nothing except what is donated to them. Once a day the group walks through the town holding small baskets for offerings. Main purpose is to recieve their food for the day. Most families believe it is good luck to give the group small foods that they can spare. The group is very grateful for the donations and all bow in unison to each that gives a donation much to the amusement of many kids that enjoy giving the donation.
