Xu Zhao left his job a year and a half ago, and his old company is still using his signature.
Four people were trapped in the elevator, but his mobile phone received a notification: the repair was completed and the customer was satisfied.
It's signed by him, the faceless maintenance man in the elevator, also wearing his old work clothes.
When he wrote 'the fault has not been rectified', the floor of the car reappeared.
Uncalled return calls began to ring, and the stairs that had been accepted would never come to an end.
Someone made the problem disappear from the record, and Xu Zhao had to bring out the people who were still inside.
Characters, institutions, and events are fictitious.
