"Zheng Xiao Tu," which means "Zheng Bunny" in English, is the nickname of the character Zheng Nanyin in the drama. To better understand the role, the actress who played the character, Li Tingting, brought a stuffed bunny with her during filming.
The female lead actress Ma Yili is a long-time fan of the original novels on which this TV drama is based. Back in 2010, she had read the original novels and shared her thoughts on her Weibo.
The male lead actor Bai Yu once said in an interview, "Isn't it a fact of life that those we love may betray us?" This resonates with line spoken by his character Zheng Xijue in the drama, "Isn't family supposed to drag each other down?"
Bai Yu's character in "Take Us Home" is a middle school physics teacher named Zheng Xijue. Coincidentally, the school where his character teaches was filmed in the same location as the university where Bai Yu's character, Jiang Yang, studied in the drama "The Long Night".
Xiong Xiaoling, the producer of the drama, stated that the casting of Bai Yu was perfect. Prior to this project, both the director and Xiong had worked with Bai Yu. When they read the novel and the script, they had already heard rumors that Bai Yu would be playing the role. They imagined Bai Yu playing the character Zheng Xijue in the reading process, and the fit with the character was perfect. Throughout the process, they also discovered many similarities between Bai Yu and the character Zheng Xijue in real life.
