Building 21 Does Not Exist

The property has been changed, and the newly issued "Owner's Code" has eighteen articles. Rule 1: Don't say hello to your neighbor at night unless you can confirm his shadow. Article 2: After the square dance music stops, please go home immediately and do not look at the face of the lead dancer. … Article 18: There is no Building 21 in this community. And I just sold the house in Building 18 and moved into Room 1804 in Building 21. On the first night of moving, the sound of children hitting a ball came from the ceiling. The real estate agent said: No one lives upstairs. At two o'clock in the morning, someone knocked on my door three times. In the cat's eyes, a vague figure waved to me. Rule No. 1 Says: Don't greet your neighbors. But what if the neighbor greets me first? What's even more terrifying is—— I don't know when there was a scratch on my wrist. And this isn't the first time.
