Cuijiayan Maijue is a volume, also known as Cuizhenren Maijue, Zixu Maijue. Recent research suggests it was attributed to the Song Dynasty's Cui Jia-yan (Zixu), but was actually written by Cui's third-generation disciple Zhang Dao-zhong in the third year of Tianli (1330). The original title of the book was Xuanbaizi Xiyuan Zhengpai Maijue, abbreviated as Xiyuan Maijue.

Cui, recognizing the difficulty in understanding pulse theory, stating that "it cannot be conveyed by words nor depicted by diagrams," compiled Maijue based on Nan Jing, Wang Shu-heMaijing, and Gao Yang-shengMaijue. The book uses the floating, sinking, slow, and rapid pulses from Nan Jing as its framework, with wind, qi, cold, and heat as the main diseases, providing a concise and clear overview. It employs a four-character rhyming style to elucidate the principles of pulse study, making it highly accessible for beginners. The entire book consists of 682 sentences, each with 4 characters, totaling 2728 characters, and can be divided into several natural sections based on content. It provides detailed discussions on the physiology of pulses, the relationship between pulses and yin-yang, qi, blood, nutrient-defense, pulse diagnosis locations, methods of pulse diagnosis, the six parts corresponding to zang-fu organs, the upper, middle, and lower parts corresponding to the triple energizer, the seven exterior pulses, the eight interior pulses, the nine path pulses, apoplexy pulses, cold-damage disease pulses, summerheat dampness pulses, warm disease pulses, various Zabing pulses, six meridian abnormal pulses, women's pulses, children's pulses, seasonal pulses, five zang-organs pulses, pulses of fat, thin, tall, and short individuals, and more.

Cui's Maijue mentions 27 types of pulse manifestations: floating, hollow, slippery, full, wiry, tight, surging, sinking, faint, moderate, rough, slow, hidden, soggy, weak, long, short, empty, hurried, knotted, intermittent, firm, moving, thin, leather, scattered, and rapid. The book is concise and profound, highly valued by medical practitioners throughout history. Dongyuan Shishu placed it at the beginning of the text, and Li Dong-yuan added marginal notes (according to Siku Quanshu Zongmu Tiyao, "Cuizhenren Maijue, one volume, was traditionally attributed to Zixu Zhenren, with annotations by Li Gao, the Elder Dongyuan... Dongyuan Shishu placed it at the beginning, but whether the marginal notes were indeed by Li Gao is unverifiable."). In the Ming Dynasty, Li Shi-zhen's father Li Yan-wen revised it and renamed it Siyan Juyao, and Shizhen included it in Binhu Maixue. In the Qing Dynasty, Li Yan-shi further edited the contents of Cui and Li, incorporating them into Maijue Huibian. This set a precedent for using the four-character style in pulse study literature, demonstrating its profound influence. However, the claim that pulse-taking is a "secret of heaven, a divine revelation" is somewhat mystical.

Cui's Maijue original text is included in Dongyuan Shishu, Gujin Yitong Zhengmai Quanshu, Chenxiuyuan Yishu Qishi'erzhong, and other medical collections, but no standalone edition has been found to date.

According to the Chinese Medical Classics Examination , it is recorded: "This book (referring to Cui's Maijue ) Dongyuan Shishu and the Orthodox Medical Lineage contain only its mnemonic verses. As for the full text, it has never been known to the world. The Ming Dynasty manuscript Youyou Xinshu stored in the secret archives, with five types of pulse books appended, begins with Cui's original book, titled The Secret Teachings of Maijue by the Purple Void Immortal ." Upon investigation, the Ming Dynasty manuscript Youyou Xinshu stored in the secret archives has not been seen in circulation, thus, the full text of Cui's original book cannot be verified. The 1981 Chinese medicine ancient books publishing house's facsimile of the Song Dynasty Liu Fang's compilation, edited by the Ming Dynasty Chen L?duan , titled Youyou Xinshu , does not contain the full text of Cui's original book.
