Chu Cheng, courtesy name Yantong, was a native of Yangzhai, Henan. He was widely read in the classics and prescriptions (ancient classic medical formulas) and skilled in medicine. Initially, when Yu Zhang Wang Yi, the favored son of Emperor Gao of Qi, fell ill while traveling from Jiangling to the capital, his condition worsened day by day. The Emperor’s worry was evident on his face, so he summoned Chu Cheng to treat him, and the illness was cured immediately. Impressed by his ability, the Emperor promoted him to the position of Shangshu (Minister). The extant *Chu Shi Yi Shu* (Remnant Works of Master Chu) claims that women’s pulses are opposite to men’s, suggesting that the heart and lung pulses should be assessed at the chi (cun-guan-chi pulse positions, specifically the distal positions) locations; this is absurd and erroneous, likely fabricated by later generations to deceive people. Students of medicine should exercise caution.

Xu Shen, courtesy name Chengbo, was a native of Danyang. He and his elder brother Wenbo were all skilled in medicine. After Emperor Xiaowen of Northern Wei moved the capital to Luoyang, Xu Shen was appointed Zhongsan Dafu Shiyu (Attendant Gentleman of the Palace), receiving honors surpassing those of Honglu Qing (Grand Minister of Ceremonies), before transferring to Guanglu Dafu (Grand Duke of Bright Virtue) until his death.

Xu Xiong, the son of Xu Jian, served as Yuanwai Sanqi Shilang (Assistant Gentleman of the Cavalry Attendants outside the Gate). His medical skills were praised in the Jiangzuo region (south of the Yangtze River). His son, Xu Zhicai, inherited this excellence, becoming highly proficient and serving as Taichang Qing (Minister of Imperial Sacrifices).

Xu Zhicai, courtesy name Shimao, was the son of Xu Xiong. At eight years old, he could comprehend the meanings of the classics; at twelve, he became a student at the Imperial Academy. As an adult, he excelled in medicine and possessed quick wit and eloquence. During the reign of Emperor Wu, he was enfeoffed as Marquis of Chang'an County. In the fourth year of Wuding, he transferred from Sanqi Changshi (Gentleman of the Cavalry Attendants) to Mishu Jian (Director of the Secretariat). When Empress Dowager Wu Ming fell ill, Xu Zhicai administered medicine that cured her immediately. Emperor Suzong summoned him, granted him a seat beside himself, and ordered the Crown Prince to pay respects to him. He was rewarded with one thousand bolts of silk, four hundred bolts of brocade, carriages, horses, clothing, and fertile fields and gardens totaling one thousand mu. His official rank reached Jinzi Guanglu Dafu (Gold-Grade Grand Duke of Bright Virtue), Kaifu Yitong Sansi (Open the Office and Equal to the Three Excellencies), Shangshu Ling (Chief of the Department of State Affairs), and Prince of Xiyang Commandery. This account is derived from the *Book of Qi*.

Xu Zhifan, the younger brother of Xu Zhicai, held the title of Yitong Da Jiangjun (General Equal to the Three Excellencies) and also gained fame for his medical skills. He later inherited his brother's noble title, becoming Prince of Xiyang. After the fall of Northern Qi, he entered Northern Zhou. This account is found in the *Book of Later Zhou*.

Xu Minqi, the son of Taichang Qing Xu Zhifan, was skilled in medicine, well-read, and versatile. During the Kaihuang era of the Sui Dynasty, he was posthumously awarded the title of Chaosan Dafu (Gentleman of Court).

Zhang Zixin was a native of Henei. He loved literature and gained fame through his medical practice. During the Danning era, he was conscripted to serve as Shangyao Dianyu (Imperial Physician in Charge of Medicines).

Ma Siming was a native of Henei. From a young age, he studied classic prescriptions.

During the Wuping era, he held the office of Tongzhi Sanqi Changshi (Gentleman of the Cavalry Attendants with Access).

Wang Xian, courtesy name Shirong, was a native of Leping, Yangping. He was renowned for his medical skills. At that time, Empress Dowager Wenzhao, while pregnant with Emperor Xuanwu, dreamed that she transformed into a dragon wrapping around her body. Upon waking, she was startled and subsequently developed Xin Ji (Heart Disease/Disorder). Other physicians failed to recognize the condition, but only Wang Xian, through pulse diagnosis, stated it was not Heart Disease, but rather a sign of pregnancy with a male child. This proved accurate. He served in the inner palace attending to imperial medicines and was repeatedly promoted to Yushi Zhongwei (Censor-in-Chief). This account is derived from the *Book of Wei*.

Li Xiu, courtesy name Sizhu, came from a family where his father and brother were prominent in medicine. Li Xiu contributed to preparing medicines for the Empress Dowager regarding ritual and cultural matters, leading to his promotion to Zhongshi (Attendant Gentleman). He compiled a book of prescriptions consisting of one hundred volumes.

Chen Shi (known as Rihua Zi) was a native of Yanmen during Northern Qi. He had a deep understanding of drug properties and meticulously distinguished their subtle differences. His annotations and exegeses on Bencao (Materia Medica) and Jingfang (Classic Prescriptions) are still relied upon today.

Zhou Dan was a native of Jingzhao. He was skilled in medicine and served as Taiyi Ling (Director of the Imperial Medical Bureau). In the second year of Shenrui, the court discussed moving the capital to Ye. Zhou Dan and Cui Hao, the Jijiu (Master of Writing), advised against this move. Emperor Mingyuan accepted their advice and issued an edict granting each of them a servant from the maternal relatives.

Zhang Yuanyou was a native of Qi, known for his medical arts. Soon after, an edict summoned him to compound the Nine-Turn Golden Elixir (Jiu Zhuan Jin Dan) alongside alchemists. Once the elixir was completed, Emperor Xianzhu placed it in a jade casket, saying, "Greedy for the joys of the human world, I cannot ascend to heaven. You may consume it only when I am on my deathbed." This account is derived from the *Book of Qi*.

Li Yuanzhong was a native of Zhaojun. Initially, he gained fame for collecting medical techniques to treat his mother's illness, treating patients regardless of social status with utmost dedication. He eventually rose to the rank of Piaoqi Da Jiangjun (General of Agile Cavalry) concurrently serving as Zhongshu Ling (Director of the Secretariat).

Li Mi, courtesy name Xiyong, was a native of Pingji. He was upright and straightforward, possessing ambition and integrity. When his mother fell ill, he studied classic prescriptions, mastering their subtleties and saving many lives, which brought him fame. He attained high offices including Dianzhong Shangshu (Director of the Palace Household), Cishi (Governor) of Jizhou, and Marquis of Ancheng County, with a fief of four hundred households.

Cui Jishu, courtesy name Shuzheng, was a native of Anping, Boling. Orphaned young, he showed keen insight, studied the classics and history, and became famous for his expertise in medicine. All these accounts are derived from the *Book of Qi*.
