At the end of the second floor is my grandmother's studio. A wooden door with peeling paint is closed tightly, and a faded red rope is tied to the door handle. Qi Yao remembers that her grandmother would stop her gently but firmly every time she wanted to go in.
"Yao Yao, there are grandma's 'gadgets' there. Children will have nightmares after seeing them." Grandma always said this, with a mysterious smile on her wrinkled face.
