Marrying Down in the 1970s

Blurb:

Xiangcao was born without a father, only a mother. Her mother said that they had been raised by a big yellow dog.

When her mother was so weak after giving birth that she was about to die, the big yellow dog stole fish from the production team's pond and saved them both.

When Xiangcao was little and cried from hunger, the big yellow dog stole eggs from the production team's chicken farm and kept them both alive.

Later, when her mother fell seriously ill and needed money, the big yellow dog carried Xiangcao, who was a little over two years old, and found her biological father.
