The creative inspiration of "Spring Silkworm" comes from a news in the newspaper that "there was a bumper harvest of spring silkworms in eastern Zhejiang this year, and silkworm farmers went bankrupt one after another". The work is based on the water town in the south of the Yangtze River, with sericulture as the main line. This paper describes the tense and hard work of the old sericulture family, which won an unprecedented harvest of spring silkworms, but instead owed money to sell the land, resulting in "mulberry field loss 15 bears leaves and owes 30 yuan", reflecting the cruel social reality of rural economic depression and farmers' bumper harvest in the early 1930s. The work not only gives a true description of the reality, but also shows the decline history of modern rural areas in China from the perspective of an old farmer through the memories of the past by old Bao Tong.
