Jiang Li, earning a monthly salary of 3,500, rented a haunted house for a monthly rent of 300. That night, a Qing dynasty female ghost drifted in front of her bed. Instead of running away, she pulled a 90-cent shared rental agreement out from under her pillow, "Sign here, and we'll take turns taking out the trash." From then on, she and a Qing dynasty young lady became roommates. The female ghost had severe germophobia, complained about her eating instant noodles, helped her fold her underwear, and fiercely criticized modern variety show VIPs. A year later, in a print shop, a girl in a white dress pushed open the door and said with a frown, "Today's roommates are so unrefined." Jiang Li pulled out a pen, "This time, we'll sign with a pen."
