八。
巳亥为四。圆图无此。而缺三焦包络。大抵书之有图。所以彰明其理耳。今反晦之。是以不
录。窦氏井荥俞经合应日开阖。有图有说。今人泥其图而不详其说。妄言今日某日。某时其
穴开。凡百病皆针灸此开穴。明日某日。某时其穴开。凡百病针灸明日开穴。误人多矣。今
去其图。直录其说。使人知某病宜针灸某经某穴。当用某日某时开方针。如东垣治前阴臊臭
。刺肝经行间。用乙丑时矣。又刺少冲。则宜丁未日矣。岂东垣治一病而有首尾越四十三日
刺两穴哉。此又不通之论也。大抵医自素、难之下。皆为旁 曲径。非周行也。

The above describes the opening and closing hours of the Zi-Wu Liu Zhu method. Originally, there were two diagrams: a square diagram and a circular diagram. Now, only the text is recorded directly for ease of memorization. The old square diagram designated Jia-Ji as nine, Yi-Geng as eight, and Si-Hai as four. The circular diagram did not have this classification and lacked the Sanjiao and Pericardium. Generally, books include diagrams to clarify principles. However, including them here might obscure understanding, so they are not recorded. Dou Hanqing’s theory of Jing-Well, Ying-Spring, Shu-Stream, Jing-River, and He-Sea points corresponding to daily openings includes both diagrams and explanations. Modern practitioners, however, stick rigidly to the diagrams without studying the explanations, falsely claiming that on a specific day and hour, a specific point opens, and all diseases should be treated by needling this open point; or that tomorrow another point opens, and all diseases should be treated then. This has misled many. Therefore, the diagrams are removed, and only the explanations are recorded, so that one knows which meridian and point are suitable for a specific disease, and which day and hour correspond to the appropriate needle-opening technique. For example, Li Dongyuan treated foul odor from the external genitalia by needling Xingjian of the Liver Meridian at Yi-Chou hour; and if needling Shaochong, it would be appropriate at Ding-Wei day. Could it be that Li Dongyuan treated one disease over forty-three days, needling only two points? This is an illogical argument. Broadly speaking, since the *Suwen* and *Nanjing*, medicine has deviated into side paths and crooked trails, rather than following the continuous, orthodox flow.
