Other than the tape and newspaper article, Chen Ge found many other hints about Xu Zhenzhen inside the office. For example, in a broken photo frame left in the corner of the bookshelf, there was a picture of a father and daughter, but both of their faces had been blocked out. There was the man's will inside the table's drawer, and it did mention the name Xu Zhenzhen. There was not one picture of Xu Zhenzhen, but the mention of the girl's name could be found all over the Haunted House.
Tian Teng Medical School is using a real case to design their Haunted House. Aren't they afraid of evoking the real Xu Zhenzhen? Haunted Houses were natural locales where negative energy gathered. It shied away from sunlight and was the perfect hiding location for spirits and ghosts. They say dreams are reflections of real life. Every day, people in the Haunted House are calling Xu Zhenzhen's name, what if she heard them?
