Stingy people wish to keep them for further use, and the poorer families cannot afford to get rid of them and buy everything anew. Isn't this lamentable, since it creates the cause of the great misfortune yet to come! This passage refers to the cause of TB in ancient medical terminology of "jiuchong" 九蟲 "Nine Worms" and "gu" 蠱 "supernatural agents causing disease", and "qi". The Nine Worms generically meant "bodily parasites; intestinal worms" and were associated with the "sanshi" 三尸 "Three Corpses" or "sanchong" 三蟲 "Three Worms", which were believed to be biospiritual parasites that live in the human body and seek to hasten their host's death. Daoist medical texts give different lists and descriptions of the Nine Worms. The "Boji fang" 博濟方 "Prescriptions for Universal Dispensation", collected by Wang Gun王袞 (fl. 1041), calls the supposed TB pathogen "laochong" 癆蟲 "tuberculosis worms". This "Duanchu shizhai pin" chapter (23/7b-8b) explains that the present Nine Worms does not refer to the intestinal "weichong" 胃蟲 "stomach worms", "huichong" 蛔蟲 "coiling worm; roundworm", or "cun baichong" 寸白蟲 "inch-long white worm; nematode", and says the supposed six TB worms are "six kinds" of parasites, but the next chapter (24/20a-21b) says they are "six stages/generations" of reproduction. Daoist priests allegedly cured tuberculosis through drugs, acupuncture, and burning "fulu" "supernatural talismans/charms". Burning magic talismans would cause the TB patient to cough, which was considered an effective treatment. To cure the disease, it is necessary to produce a spout of smoke by burning off thirty-six charms, and instruct the patient to inhale and to swallow up its fumes, whether he likes it or not. By the time all charms are used up, the smoke should also be dispersed. It may be difficult for the patient to bear the odour of the smoke at first, but once he gets used to such a smell, it does not really matter.
