Among the above formulas, except those specified as "not suitable for decoction powder" (Zhusan Fang), for all liquid preparations where "Ju" (chewing or crushing herbs into a coarse residue similar to lotus root dregs, i.e., current coarse granules) is mentioned: take four qian per dose, add one and a half zhan of water, boil down to eight-tenths, filter out the dregs, aiming for seven-tenths of the final volume. If the formula contains toxic herbs such as Banxia (Pinellia Rhizome) or Fuzi (Prepared Aconite Lateral Root), take four qian of herbs per dose, add two zhan of water, include three slices of fresh ginger, and boil down to seven-tenths. If the formula uses Puxiao (Mirabilite), Ejiao (Donkey-hide Gelatin), Yitang (Maltose), Yanxiao (Saltpeter), or Jiziqing (Egg White), these should be added after the decoction is finished and filtered. If Zhuli (Bamboo Sap) is used for decoction, take four qian of herbs per dose, add one and two-tenths zhan of water, boil down to seven-tenths, then add three parts Zhuli, and boil again until seven-tenths remain. If Dahuang (Rhubarb Root and Rhizome) is used: for deficient persons, decoct Dahuang together with other herbs; for difficult-to-evacuate persons, take four qian of herbs per dose, add one and a half zhan of water, boil down to one zhan, then separately add half a qian of Dahuang, and boil together until seven-tenths remain; for those extremely difficult to evacuate, soak concentrated Dahuang juice in the decoction for two or three parts, boil together, and stop when evacuation is achieved.

Pang Anchang (Pang Anshi) loved medical formulas since childhood. In treating patients, his judgments on life and death were often accurate, and his fame overshadowed other physicians in Huainan. However, he was bold and chivalrous, engaging in cockfighting, dog-running, soccer, and ball games, doing everything associated with youthful extravagance. He excelled at chess (Yi), a skill difficult even for artisans to master. His family was wealthy with many concubines, and he could obtain what he desired without leaving his house. When hired by others to practice medicine, he would elaborate on his hobbies to please them. Patients flocked to his home like a market; once cured, he would depart gracefully without accepting rewards. In middle age, he abandoned play, closed his doors, and studied. From the Classic Formulas of Shennong and Huangdi, Bian Que's *Eighty-One Difficult Issues* (*Nanjing*), to Huangfu Mi's *Jiayi Jing*, he mastered them all. Where bamboo slips were disordered, yellow silk rotting and worm-eaten, and ancient masters' meanings lost; where shallow scholars made arbitrary interpretations, and narrow-minded individuals tampered with texts, Pang Anchang could辨析 and expound upon them. Using these in treatment, he achieved nearly ten cures out of ten. Yet, regardless of wealth, he treated patients who came to his door, providing comfortable rooms, adjusting for seasonal comfort, offering fine foods and vegetables, and regulating their hunger and fullness. He loved the elderly and cared for the young, never using people's illnesses to test his prescriptions, as if the pain were his own. He regarded wealth as dirt, endured tasks with maternal patience and consistency, resembling the chivalrous warriors of Qin and Han without harming others, and resembling the Four Lords of the Warring States without seeking profit. Thus, he acted with ease and satisfaction. The number of diseases he cured was incalculable. Later visits brought no trace of pride. His compiled *Treatise on Cold Damage* (*Shanghan Lun*) consisted of his daily-use books. He wished to extract the essentials and discuss the subtleties so that scholar-officials might understand them slightly. However, those who had not visited his courtyard would not understand even my explanation; those interested in this field could explore its subtleties sufficiently by reading his book alone, hence I do not elaborate further. I record his deeds as a postface. The previous preface was written by Renuo from Haishang, so the right side is left blank.
