Symbolism in "The Road Home"

One of the most prominent symbols in The Road Home is the loom. Zhao Di (the mom) is seen looming in the flashbacks to make a banner for the schoolhouse, and in present-day as she makes a cloth for her husband's funeral. Because the loom is old and broken in the present-day scenes, I think it symbolizes a desire to hold on to the past, and to old customs of Chinese tradition. Zhao Di used the loom in the past when she first got to meet her husband. She uses again to mourn the loss of her husband. It is something that meant a lot to her in the past, and she still wants to use it as a way to hold on to the past.
