Copy the following paragraph from the introduction of the work:
Tan Tingyan is an old house restorer who was banned from the industry. He inherited the studio left by his grandmother as soon as he lost his job, as well as a debt of 800,000 yuan. Every time she repaired real house damage with her own hands, she could hear the ten seconds of sound left behind when the damage was done. Sound cannot be recorded, nor can it be directly used as evidence. She must rely on inspection, restoration and physical evidence to find out the truth hidden in the wall.
The first commission came from an aunt who lived alone and was preparing to sell her house at half price. The agent claimed that the house was haunted, with people knocking on the wall every night; Tan Tingyan repaired the wooden lining behind the mirror, heard the sound of an electric drill and the words "mirror to the left", and found the hidden device.
From wedding houses whose prices were maliciously lowered, to community childcare centers with structural dangers, to old buildings that all residents said had never seen fire, she took orders to pay off debts while forming a female restoration team. They not only repair a wall, but also help people who have been priced out and whose truth has been concealed to regain their lives. The last account book left by her grandmother is leading her to her mother who disappeared three years ago.
