Bells are
considered luck items in Chinese traditions. Bells are rang 108 times to begin
a grand celebration. The digits are derived from the idea of 12 months, 24 solar terms and 72 hou (5 days a hou) on the
Chinese lunar calendar which means 108 worries will be removed from the people.
It can be compared in the 40 days mourning period of the family with a dead
family member which means that only after 40 days will the dead realize the
he/she is dead.
