"Tongnian River" tells the story of the growth of boys and schoolmates with Shanghai as the background in the 1950s and 1960s.

Tong Nianhe tells the story of the growth of the boy Xuedi with the background of Shanghai in 1950s and 1960s.

There is a boy named Sidi in a family. The story of Xuedi and his mother-in-law (grandmother): Xuedi's mother-in-law played a lot of jokes and told many interesting fairy tales because she was illiterate, which benefited Xuedi a lot and guided Xuedi to grow up.

After returning to Shanghai from the countryside, Xuedi has the deepest feelings with her mother-in-law. They also have an old cat who loves the old and the young. At the end of the old cat's life, his two sons (white cat and black cat) were as sad as people.

Because she doesn't live with her mother-in-law, Xuedi often goes to her mother-in-law's house to chat with her. Once, Xuedi ran to her mother-in-law's house again, and suddenly found that there was no trace of the old cat in her mother-in-law's house. After some inquiries, I realized that the old cat was hidden to let the white cat and the black cat survive. Later, a big white cat with green eyes appeared on the roof of my mother-in-law's house. After many twists and turns, my mother-in-law realized that the white cat on the roof was the mother of an old cat and also a Persian cat.

Soon after, the old cat died, and her mother-in-law fell ill because she was too sad. In the hospital bed, she told Xuedi a story about this Persian cat: this Persian cat was brought back from outside by her husband (who has passed away). Later, fearing that the Persian cat was too beautiful, many people would like it and took it away. My mother-in-law climbed onto the roof with the old cat (then a kitten). There is a cupboard on the roof, where my mother-in-law puts her clothes. My mother-in-law put the Persian cat in the cupboard, but the Persian cat couldn't get out. It was a rainy night, thunder rumbled, lightning flashed and thundered. My mother-in-law thought, why hasn't the rain stopped? As a result, my mother-in-law was awakened by thunder and found that her cat had disappeared. Later, a few months later, it gave birth to eight kittens (including the old cat now), and then they lived together for many years (the Persian cat grew bigger). Until one day my mother-in-law saw someone holding a Persian cat on the beach. Later, the Persian cat died, and her mother-in-law was very sad.

But soon after, her mother-in-law passed away, and Snow Emperor was very sad. He remembered his fond memories with his mother-in-law: he helped her dye the cloth; Mother-in-law gave him a big and bright firefly; He and his mother-in-law are looking at the stars on the roof ... He also thinks of the white cat: it sends Xuedi to school every day; Waiting for his schoolmate to leave school on the roof ... He couldn't help thinking silently: Animals also have feelings, so we must cherish them.

Finally, Xuedi remembered the story with her mother-in-law: her mother-in-law gave him a book called Pupils Pictorial, which contained earthwork. Another day, my mother-in-law saw an Indian selling balloons on the roadside, so she bought A Le Ballon Rouge and gave it to Snow Emperor. The balloon flew into the sky and left a red memory in my heart. ...
