Step-by-step explanation:
When the boy in the novel 'When the Emperor was Divine' receives a Swiss Army knife as a surprise gift, it serves as an important emotional anchor for him. This gift likely symbolized a connection to his father, which would have brought him significant comfort during a time of separation and uncertainty. The prestige goods mentioned in the historical background signify not only wealth but emotional and political power, which can relate to how the Swiss Army knife would symbolize both practical utility and emotional value for the boy. In the setting of the book, where characters are displaced and dispossessed, having something that represents a link to one's past and loved ones would indeed be a source of comfort and emotional support.
