If a mother nurses while pregnant, it may cause illness in the infant, such as malaria or dysentery; children born subsequently may also sequentially develop abdominal distension, with symptoms either manifesting or remitting. It is advisable to wear feathers from the *Bailao* bird (also known as the *Bola* bird), or place *Yeming Sha* (Bat Guano) inside a red gauze pouch for the child to carry.

The monks of Zhulin Temple in Xiaoshan were renowned in eastern and western Zhejiang for their specialized treatment of gynecological diseases. My residence was less than fifty kilometers from the temple, yet despite seeking their medical texts, I had never seen them. In the Gengxu year of the Daoguang reign, my brother-in-law, Mr. Zhang Chuntang, presented me with this book. Upon trial according to its prescriptions, efficacy was immediate. When asked about its origin, he stated it was obtained from a local gentry family in Jingde County, who retained a copy. However, the author's name was not transmitted; inquiries among physicians yielded no answers. Some suggested that the title "Zhulin" implied a secret transmission from the temple monks, a view I endorsed, and thus stored it in my chest. In the Xinyou year of the Xianfeng reign, Taiping forces captured our prefecture, and this manuscript, along with other books, perished in the flames. During displacement and migration, the absence of this text was often felt as an inconvenience. During the Tongzhi era, upon revisiting the waters of Anhui, I searched extensively but found nothing; inquiries regarding the original woodblocks printed by the Wang family of Jingde revealed they too had been destroyed by war, leaving not a single block remaining. In the Xinshi year of the Guangxu reign, borrowing the printing blocks preserved by Chuntang, I planned to have them carved and published, but lacked funds. Therefore, utilizing spare time from official duties, I manually copied the volume into a booklet and returned the original to him. Relatives and friends learned of the copy and borrowed it through various channels; some attested to its miraculous efficacy, clearly curing frail women in the inner quarters and infants in swaddling clothes, offering great benefit to the world. Since it offers such great benefit, why should it not be printed and made public? Sharing this intention with like-minded individuals, all were willing to contribute. Prior to this, Mr. Chen Yousheng sent a letter presenting the formula for Heishen Dan (Black Divine Pill), calling it a sacred medicine for preserving childbirth. Yousheng studied medical classics meticulously, was skilled in treating diseases, and his reputation and integrity spread throughout our prefecture. I deeply respected his theories, sourced high-quality aged ink, and requested he prepare it strictly according to ancient methods. Soon after, he generously shared it with me; every application proved effective. Once, I saved a woman facing critical difficulty in labor when other physicians were at a loss, further validating the claim of "sacred medicine" with concrete evidence. This sufficiently supplemented content missing from this book. Coinciding with the completion of the craftsmen's work, it was appended after the section on preserving childbirth to facilitate wider dissemination. Mr. Zhou Chun, Fang Dijie, Chen Xingfu, Lu Zhan, Zhu Hutang, Zhang Ganchen, Xu Bore, Yang Zishou, Tan Mengbai, Huang Youtang, Shen Shunqing, Bu Zhou, Baoqing, Xu Ziying, Chen Peisheng, and Yang Yunjie all contributed funds. Mr. Po Lengqing assisted continuously throughout the carving process. Mr. Zhang Yiming and Mr. Wu Zijian were responsible for proofreading. These details are recorded briefly at the end to clarify that a long-held hidden wish has finally been fulfilled, relying significantly on the support of friends.
