In China, every family worship a "kitchen god" in their kitchen. At the end of the year, this god will go back to the heaven to report how this family did over the past year. The family made this sticky ball to glue the mouth of this god in order to prevent him from saying anything bad about the family.
Nowadays, these sweet ball also means reunion due to the round shape. It usually served in sweet soup made of brown cane sugar and ginger. The stuffing can varies from peanut paste to red bean paste.
