What is an example of symbolism in the novel, Daughter of Moloka'i?

Chopsticks symbolize Japanese culture. When Ruth first comes to live with the Watanabes, she is not able to use the chopsticks. The family understands this and gives her a fork while she learns. Eventually she does learn as she learns other Japanese customs. When the family gets to the internment camp, they are not given chopsticks, only traditional Western dining ware. This symbolizes a lack of concern and a hostility towards Japanese people and customs on the part of the American government.
