"Spring Silkworm" is set in the countryside of Jiangnan. It is irrefutable that farmers in old China must find a real way out beyond the bumper harvest of that year through the fact that the farmers' old Bao Tong family had a bumper harvest of sericulture, but their lives were even more difficult. The novel puts the characters in such an era background by fictional writing: just after the "December 28th" Sino-Japanese War in Shanghai, the national silk industry went bankrupt due to the dumping of foreign goods, and there was no market for silk, the main by-product of farmers in the south of the Yangtze River; The usury exploitation of feudal landlord class is more cruel; Capitalists also took the opportunity to depress the purchase price of silk. It is under such circumstances that after a month of hard and intense sericulture, the people in Laotongbao Village have achieved a cocoon harvest that they have not seen for many years, but the harvest has brought them more poverty and disaster instead of wealth and happiness: "Because the spring silkworms are ripe, the people in Laotongbao Village have increased their debts! Old Bao Tong's family ... lost fifteen mulberry fields and thirty dollars in debt for nothing! It doesn't count to stay up late for a month with an empty stomach! " Old Bao Tong is a hardworking, honest and conservative farmer of the older generation. He analyzed and treated what was in front of him with the experience of "living for 60 years and experiencing several years of anti-chaos". He realized that the world was "getting worse and worse" because of foreign devils, so he hated not only foreign devils, but also everything with the word "foreign". He loves labor and thinks that life can only be improved when the fields are ripe and the silkworms are harvested. He also believes in fate and ghosts and gods, and obeys them devoutly, and wants his son Addo to abide by all the taboos when raising silkworms. The times have changed and the surrounding environment has changed, but his thoughts have not changed, which is an important reason why he became a tragic figure. His son, Addo, has a different personality from him: he doesn't believe that a ripe field or a good harvest of silkworms can change his poor fate; He is not as sad as old Bao Tong, and he is always optimistic about the world. He began to think more deeply about social phenomena. "He feels that there is something between people that can never be made up", although he still "doesn't understand where it is or why". In this way, the novel describes the conflict between two generations in rural areas of old China in 1930s on how to get rid of poverty. The gradual growth of farmers of Addo generation and the gradual awakening of farmers of old Bao Tong generation have become the inevitable trend of rural development in old China. This trend is revealed in Dong Can after Autumn Harvest and Spring Silkworm. Autumn harvest, when the soap bubbles of old Bao Tong's "mature year" were completely burst, thus sending away his hard work, the initial awakening consciousness was revealed in his "bright and bright" eyes. "Nengdong" further describes the deepening of rural disasters and the rise of peasant resistance. These three consecutive short stories were called "rural trilogy" at that time; They truly reflect the profound sufferings of the broad masses of peasants and their historical trend of awakening from conservatism and chaos and finally struggling. Especially Spring Silkworm, the whole work is like a movement interwoven with farmers' hopes, worries, joys and disappointments, which makes readers' mood fluctuate closely with the development of characters' fate. The latter two plots develop too fast, the development of characters is not clear enough, and the characters are not as full and vivid as Spring Silkworm.
