"They don't get to rename them," Wan said firmly. "Yèwǎn and Tiān were given to you to care for them. You are the only one who gets to rename them. Though if you prefer calling them Night and Day, that's okay. I wasn't sure how to spell night when I filled out the adoption papers so I just used the Chinese characters for both. I had someone at the Owl Post tell me how to spell 'Night' when I wrote to you."
