Willow tree.

When I visit Western Springs, I cannot walk past this "willow" 柳 /liu tree without thinking of my dad's lesson. He told me willow represents a brothel in Chinese.

In the book. young girls were taken by the Japanese soldiers to become their comfort women. I didn't want to use the word willow. These girls were forcefully abducted. I chose the name Cherry Blossom Inn instead.
