The Leisurely Daily Life of a Train Porter in the 1970S

The author writes very well, and the story is eloquently told, just like a very ordinary life, but one thing I am very surprised about is that we didn't live separately after getting married, so why is there no description of Zhou's mother? She just lives in a separate house, but in the following pages, whether she is eating, stocking up on winter vegetables or pickling pickled vegetables, Zhou's mother never appears. She seems to be a tool person who comes out when needed.
