There are people in the world who seek prescriptions through *Ji Fang* (divination by a planchette to summon spirits). The prescriptions they obtain indeed include those that are extremely shallow, crude, and unorthodox, which not only fail to cure diseases but also harm patients. However, there are also those that are extremely profound, ancient, unique, and stable, yielding miraculous effects when used to treat diseases. These "immortals" may claim to be Lu Dongbin or Zhang Zhongjing. Their prescriptions appear to be the legacy methods of Lu Dongbin and Zhang Zhongjing. Although this phenomenon is strange, there is logic behind it. "Ji" refers to spiritual sensitivity. The human heart's appeal to the divine is all-pervasive; since one sincerely seeks healing, ghosts and deities capable of curing must respond. Although these are not the true Lu Dongbin or Zhang Zhongjing, they are likely enlightened physicians from past lives who died without meeting their time. Their spirits, lingering between heaven and earth due to unresolved attachments, arrive upon sensing the call to demonstrate their abilities. If a patient's condition is at a stage where recovery is possible, such an encounter occurs, which is also logical. These prescriptions may not all be effective, but they invariably possess meaning, unlike contemporary mediocre physicians who use contraindicated herbs to harm people. They simply refuse to speak definitively about life-and-death prognoses, as heavenly secrets are not lightly revealed. As for prescriptions that are incoherent or unorthodox, they result from poor proficiency in the planchette technique or lack of sincerity from the patient, and thus are not genuine *Ji Fang*.

Regarding drug errors, even if a medicine does not match the disease, if it is not contrary to the pathology, it cannot kill. Even if it is contrary to the pathology, if its nature is mild, it cannot kill. If it is contrary to the pathology and has a harsh nature but is administered in a light dosage, it cannot kill. If the nature is contrary and the dosage is heavy, but the formula contains several herbs that target the disease or ingredients that can neutralize the toxic nature, it cannot kill. Furthermore, if these harms are combined with either a very mild disease or robust vitality, death still does not occur. Thus, killing via erroneous medication is so difficult that although most physicians make mistakes, we do not see them killing several people daily. Even if death occurs, it is usually due to prolonged delay and neglect, causing the patient to die without realizing the cause. If the patient fortunately survives or gradually recovers, they mistakenly attribute this to the efficacy of the erroneous prescription and subsequently use it to treat others. Consequently, they mislead people throughout their lives without recognizing their own fault. Only excessively hot and dry medicines kill most violently. Hot-natured herbs are often toxic; moreover, Yang heat is fierce and rapid. Once entering the Zang-Fu organs, it causes blood surging and Qi ascending. If the patient's Yin Qi is inherently deficient, or if it is peak summer heat, or if the patient suffers from heatstroke or internal heat, administering a hot formula creates a conflict of two fires. This results in red eyes, constipation, dry tongue, dry teeth, thirst, irritability, skin cracking, and restlessness—all severe symptoms erupting simultaneously. Physicians and families fail to observe this correctly; some suggest "guiding fire back to its source," while others claim it is a *Yin Syndrome* and advise increasing the dose of hot herbs supplemented with major tonics. The patient then bleeds from all seven orifices, cries out in agony, and resembles someone who has taken poison. The family does not consider it their fault, and the physician remains complacent, believing the disease progression was inevitable. In short, foolish people prefer taking tonic and hot medicines, regretting nothing even in death. I have witnessed this enough times to weep bitterly, yet neither physicians nor families listen. Is this not what is called destiny? Cold medicines can also kill, but the process is slow and potentially salvageable; unlike hot medicines, which are absolutely incurable once administered. As for extremely mild and bland medicines, erroneous use can also kill, but this is because the patient's constitution is extremely weak or the condition is already critical. Thus, minor errors lead to drastic changes, and this cannot be entirely blamed on the physician killing the patient.
