Yang Yang, a 22-year-old fresh graduate from the History Department of Nanjing Normal University, was criticized by Yan Li and other reviewers during the defense for his graduation thesis, which focused on three generations of the Gu family in Biyuchun, Nantong, to study the rituals of Poxue Lake. Due to the lack of official historical support, his instructor Professor Liu used a rare and unique manuscript to win him the opportunity to conduct field research in Nantong for half a month.
Yang Yang returned to Nantong and found the tokens of three generations of the Gu family and the fragmentary pages of the original book of Poxue Lake at the place of her grandmother Gu Chunhe. She learned that her great-grandmother Gu Biyao refused to perform the Poxue Lake atonement ritual that had been tampered with by feudal clan elders in the late Qing Dynasty, and created the dish with the craft of "one pack, two dishes and three o'clock". The establishment of Bi Yu Chun; the great-grandmother Gu Yuwan fell in love with underground worker Jiang Zhenting when she was guarding the restaurant. She stayed in the restaurant during the war, but waited for the bad news of her husband's death; the grandmother Gu Chunhe was persecuted in special times, but still tried her best to protect the family's tokens and crafts.
Yang Yang found first-hand evidence such as Gu Biyao's folk oral records and Jiang Zhenting's martyrdom certificate in the Nantong Archives, and added them to the paper. In the second defense, she clarified the evolution of the Poxue Lake ritual from a compassionate salvation to a female yoke, and told the story of three generations of women of the Gu family who relied on craftsmanship to resist feudalism and the oppression of the times. The paper was unanimously approved and rated as excellent.
In the end, Yang Yang and Gu Chunhe restored the old site of Biyuchun, regained the family's craftsmanship, and paid homage to their ancestors at the Gu family's ancestral graves, passing on the women's tenacity and craftsmanship forever.
